How much healthy choices prolong life

I read a study this morning done by the Lancet that said worldwide Alzheimer's cases could be cut by one-third if people controlled weight, exercise, blood pressure, hearing loss and some other factors.

I think they sort of confused cause with association, but even then, it still left two-thirds of cases unexplained...not to mention sliding over whether all cases were Alzheimer's or other forms of dementia.

A study done by Health Affairs, on the other hand, took a different approach. They said 80% of those who smoked or were fat reach their fifties alive. BUT if you had not smoked or been fat, how long will you live from then on without disability?

The researchers looked at nationwide data from 1998-2012, among Americans 50 to 89.

They found the impact of a health lifestyle was large.

The average American who was not fat or did not smoke lived an additional seven years free of disability. This was better than Japan, even, where people are thought to be healthy longer.

I looked at the bar chart by risk factor...Seems the women lived longer (which we knew) but disabled was the category at the end of life, even though the disabled part may have commenced a little later than for men.

Oh, and "moderate drinker" seemed to confer a few more good yrs for both genders.
