From UPI:
Five modifiable factors can give a 70-year-old man a 54 percent probability of living to age 90, U.S. researchers found.<p.The study, published in the Archives of Internal Medicine, also found five factors that add up to an unhealthy lifestyle, which reduces that probability to 4 percent.
So what are they and how can we live to age 90?
The researchers found the probability of living to age 90 was reduced 44 percent by a sedentary lifestyle, 36 percent by high blood pressure, 26 percent by obesity and 22 percent by smoking. Having three factors together — such as sedentary lifestyle, obesity and diabetes — reduced the probability of living to age 90 to 14 percent.
The final ingredient was exercise, which obviously has positive effects.
This study was conducted only on men, probably because the way for women to live longer was decided long ago: less exposure to men.
