my Mom who died at age 86 used to say 'getting old isn't for sissies'...lol...and I think of that often and laugh.

definitely feels like it but no. really if you take care of your body as best as you can then no older than you already are physically.

YEs yes and more yes.

I would think the added stress soul make our bodies agree more quickly....

I do not believe it does. I had a friend who passed away who had that type of disease however. Her organs aged much faster than she.
