I've been seeing research report after report looking at how our lifestyle determines 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 the long and healthy life that we want. From Medical Xpress:
Live longer thanks to fruit, an active lifestyle, limited alcohol and no cigarettes. This is the conclusion of a study by public health physicians at the University of Zurich who documented for the first time the impact of behavioural factors on life expectancy in numbers.
...Brian Martin and his colleagues from the Institute of Social and Preventive Medicine (ISPM) at the University of Zurich have examined the effects of these four factors – both individual and combined – on life expectancy. An individual who smokes, drinks a lot, is physically inactive and has an unhealthy diet has 2.5 fold higher mortality risk in epidemiological terms than an individual who looks after his health. Or to put it positively: "A healthy lifestyle can help you stay ten years' younger", comments the lead author Eva Martin-Diener.
"The effect of each individual factor on life expectancy is relatively high", states Eva Martin-Diener. But smoking seems to be the most harmful. Compared with a group of non-smokers, smokers have a 57 percent higher risk of dying prematurely. The impact of an unhealthy diet, not enough sport and alcohol abuse results in an elevated mortality risk of around 15 percent for each factor.
According to Martin an unhealthy lifestyle has above all a long-lasting impact. Whereas high wine consumption, cigarettes, an unhealthy diet and physical inactivity scarcely had any effect on mortality amongst the 45 to 55-year-olds, it does have a visible effect on 65 to 75-year-olds. The probability of a 75-year-old man with none of the four risk factors surviving the next ten years is 67 percent, exactly the same as the risk for a smoker who is ten years younger, doesn't exercise, eats unhealthily and drinks a lot.

The heart is more forgiving than you may think—especially to adults who try to take charge of their health, a new Northwestern Medicine study has found. When adults in their 30s and 40s decide to drop unhealthy habits that are harmful to their heart and embrace healthy lifestyle changes, they can control and potentially even reverse the natural progression of coronary artery disease, scientists found. On the flip side, scientists also found that if people drop healthy habits or pick up more bad habits as they age, there is measurable, detrimental impact on their coronary arteries.
For this paper, scientists examined healthy lifestyle behaviors and coronary artery calcification and thickening among the more than 5,000 participants in the Coronary Artery Risk Development in Young Adults (CARDIA) study who were assessed at baseline (when participants were ages 18 to 30) and 20 years later.The healthy lifestyle factors assessed were: not being overweight/obese, being a nonsmoker and physically active and having low alcohol intake and a healthy diet.
By young adulthood (at the beginning of the study), less than 10 percent of the CARDIA participants reported all five healthy lifestyle behaviors. At the 20-year mark, about 25 percent of the study participants had added at least one healthy lifestyle behavior. Each increase in healthy lifestyle factors was associated with reduced odds of detectable coronary artery calcification and lower intima-media thickness—two major markers of cardiovascular disease that can predict future cardiovascular events. Adulthood is not too late for healthy behavior changes to help the heart."
"That loss of healthy habits had a measurable negative impact on their coronary arteries," Spring said. "Each decrease in healthy lifestyle factors led to greater odds of detectable coronary artery calcification and higher intima-media thickness.
Spring said the healthy changes people in the study made are attainable and sustainable. She offers some tips for those who want to embrace a healthy lifestyle at any age:Keep a healthy body weight; Don't smoke; Engage in at least 30 minutes of moderate to vigorous activity five times a week; No more than one alcoholic drink a day for women, no more than two for men; Eat a healthy diet, high in fiber, low in sodium with lots of fruit and vegetables.

Weight loss at any age in adulthood is worthwhile because it could yield long-term heart and vascular benefits, suggests new research. For the first time, the findings indicate that adults who drop a BMI category -- from obese to overweight, or from overweight to normal -- at any time during adult life, even if they regain weight, can reduce these cardiovascular manifestations. The findings are from a study examining the impact of lifelong patterns of weight change on cardiovascular risk factors in a group of British men and women followed since birth in March 1946.
