Ive been a runner all my life and even after 50 I continued to work out, to lift, to bike, yoga, all the stuff you are told to do. While I have been able to keep from gaining weight like most of my peers, when I get out of bed, I ache! I have terribly arthritic knees, I've been dealing with sciatica for over a year, shoulder pains.. it sucks.
But... I went on vacation for 2 full weeks and all I did was eat, drink, and walk around doing tourist stuff... I feel GREAT. Almost all my pains are gone, I actually quickly jogged up some steps yesterday.. I haven't done that in years!
I think the sedentary lifestyle my be the key to pain free living. It's like my body was saying, at 60 you need to just walk some every day, and drink beer every night.
