Living past 90, and living well, may be more than a matter of good genes and good luck. Five behaviors in elderly men are associated not only with living into extreme old age, a new study has found, but also with good health and independent functioning.

The behaviors are abstaining from smoking, weight management, blood pressure control, regular exercise and avoiding diabetes. The study reports that all are significantly correlated with healthy survival after 90.

While it is hardly astonishing that choices like not smoking are associated with longer life, it is significant that these behaviors in the early elderly years  all of them modifiable  so strongly predict survival into extreme old age.

“The take-home message,” said Dr. Laurel B. Yates, a geriatric specialist at Brigham and Women’s Hospital in Boston who was the lead author of the study, “is that an individual does have some control over his destiny in terms of what he can do to improve the probability that not only might he live a long time, but also have good health and good function in those older years.”
