How factors: love, connection, ability, and a stressful environment affect longevity?
Researching the life of people with highest life expectancy, we will hardly find the proof for economy affect directly on longevity.Jeanne Calment died at age of 122 years. Calment suggested that her longevity was to have credited her calmness, saying, “That’s why they call me Calment.” After her admission to the nursing home “Maison du Lac” in January 1985 at the age of 109, she initially had a highly ritualized daily routine whereby. Seated in her armchair she did gymnastics wearing her stereo headset. Her exercises included flexing and extending the hands, then the legs, and her caregivers noted that she moved faster than the other residents, who were 30 years younger, despite her blindness.

In nursing home:
Lack of love, lack of connection, lack of compassion make the old are more stress and do not have much enthusiasm in life.
According to the statistic of the length of stay in nursing homes at the end of life of the old, if the old come to the nursing home, the chance of the old living in the nursing home is nearly zero percent. It means that if your healthy 60-year-old enter the nursing home, the chance for them to live to 70 years old are very rare let alone they can live to 78 years old as the USA life expectancy.Length of stay in nursing homes at the end of life of the old is less than 120 months. Most of them died during the first six months and the first thirty months.
The statistic shows that the health of the old in the nursing home has some relation with the love, caring and visit of their children, grandchildren.There are stories that before the important day like national holiday, birthday and New Year, the death rate of the old reduces substantially. Perhaps, the hope, the wait, and expectation the important event with the reunion with their family members make them healthy enough to live.
Alarming the distribution of stress results all over the world:
It is lack of love, lack of connection, lack of ability, lack of understanding, and lack of compassion that cause people to live with lack of guiding by virtues, lack of gender equality, misunderstanding phenomena and causes countless bad causes. Worst of all, everyday life is covered by greed, hatred, anger and ignorance, and lots of violence, contempt in interaction, lots of violence in the act of helping others.Let look at the geographical global distribution of some factors by the search on Google.

Chronic diseases children might get depend on the development of the fetus, the stress, the stage of fetus suffering stress, the abilities of parents, the stress after being born the fetus have. It has countless varieties so I hope that science will.

The social assumptions, social paradigms put on them that make the husband has the total right to demand many things from the wife. Even the wife, from the independent being, becomes the possession of the husband. The strange man after getting married, coded by social paradigms become the dictatorial man, he has a total right to treat whatever ways he like with his wife – a strange woman previously.Watching the “Distribution of unsafe abortion per 1000 women aged 15 to 44 years around the world” and “Prevalence rates of intimate partner violence by WHO region in 2010” to understand better how ignorant human beings have rightly made with other human beings.39.

Looking at “The distribution of leading causes of lost years of life around the world in 2013” will give us a deeper understanding of the causes.

This is the tipping of the iceberg; we will have to suffer more if we do not eradicate the root.People in the stressed world find drugs like “cocaine, cannabis, amphetamine stimulants, opioids, solvents and inhalants, sedatives” to relieve pain and find temporary good state. Let look at “What drugs countries seek treatment for.” And “World Wealth level around the world in every year”45. What drugs countries seek treatment for46. World Wealth level around the world every year The pattern thinking of human beings can be found in the allocation of their asset on investment, spending, education or buying the protective weapon. We will understand the real world we are living because “all in one and one in all”. The spending of the United States on military in 2015 was $596.5 Billion that account for 54% of all spending of the United State in the year of 2015. All the major areas for stability and development like education, Medicare & health, veteran’s benefits, housing & community, international affairs, energy & environment, science, social security, unemployment & labor, transportation, and food and agriculture was less than the spending on the military.
|“Do not ask me about the stability and development when people spend major resources on a minor military, and spend minor resources on all other major sectors”|
Death rate, suicide rate, homicide rate, the percent of gender committed suicide rate, the kind diseases, health problems, teenager’s problems, mental problems, social problems and quality of life are the reflection of the big hidden problem in society.
It is the lack of virtue, goodness, kindness, and integrity in society.
Seasonal stress in the developed world
The months of less stress in all developed countries is the summer holiday.During the summer holiday, children may not suffer much stress and boring at school from the study and test. They have time to go out and play. During this time, the rate of injuries is increased and teenage death is higher than in other months.Also, do adults arrange free time same as school summer holiday for the whole family to go somewhere for holiday? The words relating to stress like “pain, anxiety, stress, depression, and fatigue” searched on the internet from the United States drop substantially during national holiday and summer holiday.During the summer month, people suffer the least stress to the rate of deaths per 100000 people reduced substantially in every country compared with other months.Look at the mortality % of yearly average in the countries: United States, Japan, Italy, France, Spain, Canada, Australia, Sweden, Greece, New Zealand, and Cyprus. Low in the summer holiday, the rise during autumn and get a peak in the winter then go down in spring.The pattern of the monthly death of the group one: United States, Japan, Italy, France, Spain, Canada, Sweden, Greece, and Cyprus have nearly the same pattern of fluctuation of monthly deaths because they have the same summer vacation time around June to September. The death rate around these months: June to September is the lowest in the years.Luckily, the low stress in the summer vacation can affect the death rate by comparing the monthly death rate of group one with group two. In group two: Australian and New Zealand, they have the same pattern of death rate, but both countries have the opposite pattern of monthly death rate compared with group one. It is because the time of summer vacation of Australian and New Zealand is from the end of December to March. So that the death rate from December to March is the lowest in the year, and the death rate from May to September is the highest in the year.The pattern of the monthly death rate of these developed countries and the death rate and injury rate during the summer vacation tell us a lot about the pattern of stress in human society. It is the seasonal stress.Furthermore, the peaks of death, the suicide rate in America and all other developed countries are in the spring and autumn. These times are the times of important examination of students in schools and universities around the developed world.The important fact is all the previous researchers have failed to indicate the correlations of temperature, wealthy, longevity, the standard of living, geographic factors with the fluctuation of death rate around the year.Does formal education is putting stress on children and stress on society is still an open question needed to answer in the future.Young people committed suicide account for a big portion of the suicidal number. Do these young people stress with the old education, money and reward culture?Recording of the death rate in the last ten centuries in Europe shows that from 1000 to 1600, the death rate of summer, spring, and fall was always higher than the death rate of winter. Until the seventeenth centuries – the time of the first industrial revolution – the death rate of winter started to over the death rate of summer, spring, and winter. Do formal education and lifestyle living of industrialization have any contribution to the monthly death rate?There is a high number of people fail in the attempt of committing suicide. However, with the popularity of using guns in some countries, the percentage failing in committing suicide by using a gun to commit suicide is very rare. According to the article “Gun control could save veterans’ lives” of Perry Stein in Newrepublic.com, in 2006, the Israeli Defense Forces made a relatively simple policy change that required soldiers to leave their weapons at their bases when they headed home for the weekend. The result: a staggering 40 percent drop in the suicide rate among soldiers aged 18-21, according to a November 2010 study.“All in one, one in all” normally, if the young kid stressed from problems arisen from family, school, society, and friend, parents and other will invisibly fall to stress too. Stress will degrade the health of all people day after day.
Cancer and stress from the discontented mind in the United States.
Seasonal stressLook at the geographic distribution of wealth, health, hygiene, social problems, health problems, mental problems in America, we will understand the illogical pattern of stress caused by the mind and condition living that effect to human beings.The distribution of “food environment index” and “severe house problems” do not match with the mental problems, health problems, social problems, and teenage problems mean that mean stress and mental state do not have the direct correlation to the quality of food, eating, and physical living as most people assumed.47. Geographical food environment index in the United States48. Geographical severe house problems in the United StatesStress problems, stress diseases belong to the mind so it has illogical patterns. Irrational stress or stress paradox is the best explanation for the American paradox of distributions wealth, health, diseases, social problems, teen problems, mental illnesses, and death rate.They have suffered the outcomes of stress.Stress comes from: lack of love, lack of connection to all other beings, and lack of ability to deal with problems and stressful situations; these lacking lead lack of understanding, lack of compassion, and lack of virtues, characters, and integrity. Over time, people distrust all things, events, and news. They live all day in fear, doubt, suspension, frustration. Their mind is full of discontentment, stress, confliction, and irritation. Where there is little trust, people start to be the slave of greed, anger and self-centered. Countless problems arise because the mind does not find peace and safe in society. The result is people are exhausted because of useless work like preparing, alerting, suspecting, and accumulating for self-protecting. These people are very weak and hurt inside. Even when the people at home, they do not feel safe let alone higher feelings of happiness. The mind starts to activate destructive stress state to prepare for a fight and flight and destroy all others feedback signals or balancing correction. Instead of healing, the minds of stressed people blindly destroy themselves.49. The rate of cancer per 100000 people by the state is high in the southeast of America.50.

Hazard distribution and frequency in the worldFood environment index is poorest in less developed areas in American. Astonishingly, the distribution of the food environment index seems to contrast with the health index of the population. This is the clue that food is not a key factor that influences the health of people.The other factor is “severe housing problems” are higher in less developed areas. This is proof that physical condition living does not influence much of the mental problems, social problems, and health problems as people usually assumed.Discontentment comes from the fact that children in poverty are severer in urban areas.The percent of preventable deaths per 100000 is American is highest with black American, and lowest in Asian American and Hispanic American. This fact may suggest that Black American are suffered the worst consequences of stress in society, and the Asian and Hispanic are suffered minor consequences of stress in society. Consequences are the combination of the love, connection, stress and ability of the individuals.January is the month of death, and the trend is increasing year after year. There are seasonal fluctuations in United States deaths. I think it matches the seasonal stress in the United States.

Ø County with the highest level prevalence of frequent mental distress among United States Adults: 2003 – 2009 is the Southeast United States or urban areas.Ø Heart disease death rates, 2008 -2010, adults, by county, highest in the Southeast United States or urban areas.Percentage of people in poverty for the past 12 months, by state in 2011; the 2011 United States poverty average is 15.9 %. The Southeast states have the high percentage of people live in poverty. The gap of standard living makes the poor become more discontent and more stressed when they compare with rich people. Arizona has 19% of people in poverty, Mississippi with 22.6% of people in poverty.According to Huffington Post, people live in urban areas of southeast America have the healthy life expectancy at age 65 is 13 years or less, whereas, people live other less developed areas have the life expectancy at age 65 is higher; some areas with 15 years or more.
Seasonal stress in America
Stress month of America is the January and February because it is the time to pay the debt by credit card. The financial burden is so heavy for them because they have overspent on the shopping season and Black Friday before Christmas and New Year.· Americans are so much stressed after overeating, overspending, and discontent with stressful work after the long holiday. So that the flu season in America in January and February. There are a lot of incidences of deaths, flu, and strokes at the beginning of the year more than another month of the year. Even the weather of spring is better than the weather of winter.· The incidences of death rates and heart diseases in The United States during the beginning of the year are significantly higher than another month of the year and similar to with other developed countries.· Americans are so much stress with the burden put on them so that the month of heart diseases is February.American misery index of 2014 searched on the GoogleLook at the daily misery index, 2014 by the keywords searched on Google are depression, anxiety, pain, stress, and fatigue. The fluctuation of the searches is also the fluctuation of stress in the United States in 2014, retrieved from “The Google misery index: The times of year we’re most depressed, anxious and stressed” by Christopher Ingraham on The Washington Post:- The searches rise in the spring and fall, ebb during the summer months, and drop sharply during holidays. Christmas is the least miserable days of the year, with Christmas Eve and New Year’s Day.
The rhythm of stress during the week:
Peaks and valleys in the raw reflect the rhythm of the workweek. People are more stressed on weekdays, less so on weekends. Weekends are the best day of the week:· Pain and anxiety peak on Mondays, these numbers suggest that people literally hurt more on Mondays or afraid of boring stressful work.· Stress and depression are high on Tuesdays. Fatigue is high on Wednesday.· Searches for all terms drop sharply going into the weekend and then edge back upward on Sunday.· The gap between weekends and weekdays shrinks in the summer months (summer holiday): those peaks and valleys are a lot closer to each other in July than they are in March and April.· The annual trend in searches for “seasonal affective disorder,” we will find that these peak in December and January. But the broader terms like “depression,” “anxiety,” and “stress,” all show a pronounced dip in December. It means that shopping, preparing, planning, waiting and expecting, and enjoying for the important and exciting days of the year make people happier than other days.· At the daily level, Thanksgiving, Christmas Eve, Christmas day, and New Year are all among the year’s least-miserable or least stressed days.· After long and expensive holiday has made people more frustrated with work, but they have to bear the financial burden of the overspending credit card for the shopping season, Black Friday, and the spending during the holiday has made the people suffer the worst stress. These may be the trigger of the stress that they have suffered for a long time.· Randomly, on Wednesday, April 23rd, 2014 the large upper-level of stress words searched were accompanying cold front draped across the Central United States on April 18. Formed April 15, 2016, and dissipated April 23rd, 2016. With snowfall, ice accretion, and rainfall near 51 cm around the Houston, Texas areas. Damage $ 2.7 billion. On 23rd April 2016 was the highest search with the stress words.· 4/7/2016 is the National Day of America. People enjoy and celebrate so the stress words search on Google is the lowest.· Perhaps, people glad and treat well with each other on Valentine day, so the Saturday after valentine day of 2016, the stress words search on Google is the lowest.· Days of New Year, Thanksgiving, and Christmas was the happiest day of American. So the stress words search on Google is the lowest.Reading this article, the facts show the reader enormously how fragile modern people are! People in wealthy countries and all over the world are fall to the rhythm of stress on society. There are no direct root causes, stress is the accumulation of countless bad behaviors. Rare anyone can escape from the effect of stress, all people are affected by stress directly or indirectly. Worse of all, the infants, babies, the young, the old, the weak are the most fragile creatures affected first, then all people in society and the whole world will suffer later directly and indirectly. The sages will show the way to get out the spiral of stress.
The South African Stress and Health (SASH) study
By observing, you will see people living in the city with a lot of facilities do not make them happy if they have a discontent mind. Even worse, by comparing with other, discontent mind can fall to extreme stress. People of South African are more stress than Nigerians are. Perhaps they do not accept or deal well with the problems as Nigerians do. They do not deal well with poverty and inequality as the Nigerians do. Lack of skills, abilities and discontent mind make them suffer more stress than Nigerian.Especially, people in cities are lack of connection with people and nature so that they fall to more stressful and mental illness compared with the people in rural areas.People and children in cities are better facilitated and fed than the people and children in the rural areas so that they lack some vital skills to deal with stress, people in cities are more stressed and get more mental illness than people live in the city. It is the skill, ability, and environment have directly and indirectly caused people stressed.The Western Cape, which has the highest prevalence of common mental disorders, was the first region of South Africa to be colonized and has a high level of urbanization. In contrast, rural provinces generally have lower rates of common mental disorders, with the lowest rates in the Eastern Cape.South Africa has a relatively high 12-month prevalence of anxiety and mood disorders when compared with the other countries in the World Mental Health Survey. Only Belgium, France, Germany, New Zealand, The Netherlands, Colombia, Lebanon, and the USA have higher rates of anxiety disorders than South Africa. And Belgium, Lebanon, Colombia, The Netherlands, France, Ukraine, Israel, New Zealand, and the USA have higher rates of mood disorders than South Africa. Hopeful that in the near future, scientists will find out detail the varieties in the cause and effect of stress on people.Only 1 in 10 Nigerians had a lifetime DSM disorder, compared with 1 in 3 South Africans. Compared with Nigerians, twice as many South Africans had lifetime anxiety disorders, 4 times as many had lifetime mood disorders, and almost 6 times as many had substance use disorders. Reasons for differences in the prevalence of mental disorders in high- and low-income countries belong to the varieties stress states in the mind of people.A recent study conducted by international research company Bloomberg, ranked South Africa as the second “most stressed out” nation in the world, following Nigeria. El Salvador was ranked third. “High-stress levels have been linked to mental illnesses such as depression and anxiety, and can also lead to substance abuse. In severe cases, these problems can lead to a person becoming suicidal,” says Viljoen, but if make a deeper investigation, people will be astonished by the results of stress and the causes of stress that they are making and bearing.
The problem of the rich: substance abuse
Psychiatric illness on the rise: South Africa already has high rates of substance abuse with, for example, alcohol alone being the third-highest contributor to death and disability among citizens, according to a 2014 study published in the South African Medical Journal.Dominique Stott from the Professional Provident Society, an insurance company for graduate professionals, said: “Rates of major mental illnesses such as schizophrenia seem to be stable but cases of depression and anxiety are certainly escalating.” Perhaps, stability in major mental illness is own for the raising high standard of living, healthcare, and insurance so that they can treat the mental illness sooner and better. But the case of depression and anxiety are escalating because these above factors do not have any influence on the poor habitual living, poor cultural living, the stressful lifestyle and the poor abilities of the individuals.
Season of stress, not the season of heat and cold
Summer break in the United States – Around 10-11 weeks, either from the end of May to early August, early June to Mid-August, or the end of June to the day after Labor Day in early September, or late June to the day after Labor Day – depending on region and state.The death rate in Canada by month from 2007 to 2011 is the same. Whereas the incidents of injury are increased substantially during these months, and the teenage deaths during these months do not reduce as the total death.During these summer days, just the small fluctuation of the hot temperature below 35 Co degrees can make changes in the number of deaths in developed countries. Temperature with 35 Co degrees is the normal temperature during the summer of people in developing countries in South East Asia, India. And it can be seen as the cool temperature in India and Africa. People in these developing countries usually live with a shortage of electricity and water during the hot summer.Lack of vital things leads them to lack the adaptability with the small changes in temperature. The temperature is not the cause of deaths; perhaps, it is the trigger to worsen the stress of stressed people in western countries.People died more because of diseases caused by stress despite the fact that the standard of living and healthcare have increased substantially.
Over 80 percent of the world’s deaths from heart disease occur in low- and middle-income countries. Stress is the product of poor interaction with too many problems and inequality. These lead to the discontent mind.Stress is illogical. The mind is irrational.These can explain the paradox that the French diet is high in dairy, fats, and red meat, these factors known to increase heart disease risk.According to Oishimaya Sen Nag from Worldatlas.com,
The top five countries with the highest rates of heart disease deaths are:
1. Russia2. Bulgaria3. Romania4. Hungary5. Argentina
The top five countries with the lowest rates of heart disease deaths are:
1. France2. Australia3. Switzerland4. Japan5. Israel
Rainbow of stress
Because of the difference in the social status, social recognition, social gender advantages, religions, instincts, abilities, talents, and skills of different gender so that men and women suffer different stress outcomes spread on the rainbow of stress.In America, suicide rates with age from 15-24 years old people, the number of males committed suicide substantially higher than the number of females.Nation sport in America caused different fatalities per 100000 students in high school after-school club activities from 1998 to 2007. It depends on the kind of fierce competitive sport or cooperative sport:Ø “Fatalities per 100000 students are highest in Judo and Rugby”, and lowest in tennis and table tennis.Ø The sports like basketball, soccer, baseball have an average number of fatalities per 100000 students.Cancer alarm at the firehouse, is it relates to stress at work? The answer is yes. Let see some clues. Stress in fighting fire is the factors that may multiply the effect of air quality of firing building. No one can imagine how stressful, how horrible, how hard in the battle with the fire of firefighters. Firefighters, their friends, the lives of people may die if they make mistake and fail.During the firefighting, their bodies have surged with the highest level of stress chemicals than the workers of other jobs that rarely anyone can imagine.The study of Harvard researchers also showed that younger firefighters had more cases of certain types of cancer, such as bladder and prostate, than expected, that chances of lung cancer increased with time spent at fires, and the chances of dying from leukemia increased with the number of fire runs. These may be the indicators of skills, abilities, and state of mind of the young firefighters.Harvard researchers led by postdoctoral fellow Emily Sparer, researchers including students from Harvard and MIT have teamed up with local fire departments to tackle a healthcare mystery: How does the firehouse itself increase cancer risk among firefighters?The research showed an elevated rate of cancer diagnoses and deaths for firefighters, mainly for the digestive, oral, respiratory, and urinary disease. In addition, firefighters were about twice as likely to develop malignant mesothelioma, rare cancer related to asbestos exposure.
