Of course! Makes sense that people who have a higher sense of purpose in life are at lower risk of death and cardiovascular disease!. From Science Daily:

Sense of purpose in life linked to lower mortality and cardiovascular risk

People who have a higher sense of purpose in life are at lower risk of death and cardiovascular disease, reports a pooled data analysis."Possessing a high sense of purpose in life is associated with a reduced risk for mortality and cardiovascular events," according to the study by Drs. Randy Cohen and Alan Rozanski and colleagues at Mt. Sinai St. Luke's-Roosevelt Hospital, New York. While the mechanisms behind the association remain unclear, the findings suggest that approaches to strengthening a sense of purpose might lead to improved health outcomes.

Using a technique called meta-analysis, the researchers pooled data from previous studies evaluating the relationship between purpose in life and the risk of death or cardiovascular disease. The analysis included data on more than 136,000 participants from ten studies -- mainly from the United States or Japan. The US studies evaluated a sense of purpose or meaning in life, or "usefulness to others." The Japanese studies assessed the concept of ikigai, translated as "a life worth living."

The study participants, average age 67 years, were followed up for an average of seven years. During this time, more than 14,500 participants died from any cause while more than 4,000 suffered cardiovascular events (heart attack, stroke, etc).

The analysis showed a lower risk of death for participants with a high sense of purpose in life. After adjusting for other factors, mortality was about one-fifth lower for participants reporting a strong sense of purpose, or ikigai. A high sense of purpose in life was also related to a lower risk of cardiovascular events. Both associations remained significant on analysis of various subgroups, including country, how purpose in life was measured, and whether the studies included participants with pre-existing cardiovascular disease..

There is a well-documented link between "negative psychosocial risk factors" and adverse health outcomes, including heart attack, stroke, and overall mortality. "Conversely, more recent study provides evidence that positive psychosocial factors can promote healthy physiological functioning and greater longevity," according to the authors.

While further studies are needed to determine how purpose in life might promote health and deter disease, preliminary data suggest a few basic mechanisms. The association might be explained physiologically, such as by buffering of bodily responses to stress; or behaviorally, such as by a healthier lifestyle.

Sense of meaning and purpose in life linked to longer lifespan

A study of 9,050 English people with an average age of 65 found that the people with the greatest well-being were 30 percent less likely to die during the average eight and a half year follow-up period than those with the least well-being.

The study, published in The Lancet as part of a special series on ageing, was conducted by researchers from UCL, Princeton University and Stony Brook University. It used questionnaire answers to measure a type of wellbeing called 'eudemonic wellbeing', which relates to your sense of control, feeling that what you do is worthwhile, and your sense of purpose in life. People were divided into four categories based on their answers, ranked from highest wellbeing to lowest wellbeing.

The results were adjusted for age, sex, socio-economic status, physical health, depression, smoking, physical activity and alcohol intake, to rule out as many factors as possible that could influence both health and wellbeing. For example, terminal illnesses could reduce both wellbeing and life expectancy.

Over the next eight and a half years, 9% of people in the highest wellbeing category had died, compared with 29% in the lowest category. Once all the other factors had been taken into account, people with the highest wellbeing were 30% less likely to die over the study period, living on average two years longer than those in the lowest wellbeing group.

"We have previously found that happiness is associated with a lower risk of death," says Professor Andrew Steptoe, Director of the UCL Institute of Epidemiology and Health Care, who led the study. "These analyses show that the meaningfulness and sense of purpose that older people have in their lives are also related to survival. We cannot be sure that higher wellbeing necessarily causes lower risk of death, since the relationship may not be causal. But the findings raise the intriguing possibility that increasing wellbeing could help to improve physical health. 

As part of the Lancet paper, the researchers also examined data on 'evaluative wellbeing', a measure of life satisfaction, and 'hedonic wellbeing', related to feelings of happiness, sadness, anger, stress and pain. International data from the Gallup World Poll confirmed that in high-income English speaking countries, life satisfaction dips around middle age and rises in older age, but the pattern varied across the world.

In the former Soviet Union and Eastern European countries, older residents reported very low rankings of life satisfaction compared with younger residents in those regions. This same pattern is seen in Latin America and Caribbean countries, though life satisfaction does not decrease as sharply as in the Eastern European countries. And in sub-Saharan Africa, life satisfaction is very low at all ages.

This is Part 3 on how lifestyle influences aging. Many recent research reports tell of a link between our lifestyle and how we'll age - whether we'll be active and healthy well into our 80s or in terrible shape and dying young. Mind you, these are not "definites" because nothing can give you a guarantee, but they are ways we can improve our odds in living a long and healthy life. From Medical Xpress:

Having a sense of purpose may add years to your life, study finds

Feeling that you have a sense of purpose in life may help you live longer, no matter what your age, according to new research. The research has clear implications for promoting positive aging and adult development, says the lead researcher.

The researchers looked at data from over 6000 participants, focusing on their self-reported purpose in life (e.g., "Some people wander aimlessly through life, but I am not one of them") and other psychosocial variables that gauged their positive relations with others and their experience of positive and negative emotions.

Greater purpose in life consistently predicted lower  across the lifespan, showing the same benefit for younger, middle-aged, and older participants across the follow-up period. "To show that purpose predicts longer lives for younger and older adults alike is pretty interesting, and underscores the power of the construct," he explains.

Education boosts brain function long after school, study shows

Education significantly improves mental functioning in seniors even four decades after finishing school, shows a new study. The study shows that people who attended school for longer periods performed better in terms of cognitive functioning than those who did not. Using data from individuals aged around 60, the researchers found a positive impact of schooling on memory scores. The fact that young people or their parents did not choose whether to go longer to school strongly suggests that schooling is the cause rather than personal characteristics that would affect this choice and could also explain the differences in cognitive function.

Lifetime of Intellectual Enrichment Keeps Aging Brain Sharp

A lifetime of intellectual enrichment helps delay onset of cognitive decline in older individuals, new data from the Mayo Clinic Study on Aging show.

In this longitudinal study, researchers found ties between higher levels of education and working in mentally stimulating jobs in early- to mid-life, as well as higher levels of mid- to late-life cognitive activity, such as using a computer, reading, and participating in social activities, and better cognition with age..."We also found that an individual with low education/occupation benefited more by engaging in high mid-/late-life cognitive activity than an individual with high education/occupation," Dr. Vemuri noted.

A number of research results were reported at the Alzheimer's Association International Conference 2014.  From Science Daily:

Potential Alzheimer's disease risk factor and risk reduction strategies become clearer

Participation in activities that promote mental activity, and moderate physical activity in middle age, may help protect against the development of Alzheimer's disease and dementia in later life, according to new research.

From Science Daily:

Physical activity is beneficial for late-life cognition

Physical activity in midlife seems to protect from dementia in old age, according to a study. Those who engaged in physical activity at least twice a week had a lower risk of dementia than those who were less active. The protective effects were particularly strong among overweight individuals. In addition, the results showed that becoming more physically active after midlife may also contribute to lowering dementia risk.
