But, don't you sometimes wonder if the study might be confusing cause and effect?  Maybe the folks walk or exercise vigrorously because they feel healthy and have a lot of energy.  That's why they have a better survival rate:  they're healthier individuals to start with.

On the other hand, isn't it possible that the group who doesn't exercise avoids exercise because they aren't very healthy and aren't feeling well.  Naturally, they don't live as long because they were unwell to begin with.

When I feel really good, I exercise a lot.  When I don't feel so good, my activity level drops.

OK, I know that's backwards thinking, but sometimes I just wonder about these studies.

And I'm not a naysayer either. My wife and I exercise regularly.

My only point, and partially in jest, is that "studies" often can lend themselves to interpretations other than what we customarily expect (e.g., exercise promotes health, but health also promotes exercise).

Sounds like a simpler summary of the study I posted on 1/10.  It started a 4 weeks activity challenge by another poster. 

Thank you for the reminder.  With March on it's way, it will be easier for the survivors north of the equator to get more walks and general outdoor activity in.  My husband, for one,  is sick of his snow shovel.
