I think the best metric is how you feel. Stuff that is called "healthy" that makes you feel bad can't really be good for you. It may be good for someone else (like the folks selling the drugs ;-). Several people I know who took statins found they really felt crappy - zapped their energy. That is definitely bad for you! Moving is good IMO. I always feel better when I can move. When we are out on the road I walk a lot. I try to get other exercise too, but often the most convenient is to just walk. Over the years various factors such as injuries and just wearing out parts of my body, I've changed activities and now do a lot of walking and weight training. The shift to more weights resulted in more muscle mass. Not a goal, just happened ;-). I mostly do weights to keep my knees and shoulders working so I can keep moving!
