Do you think staying healthy is determined by your genes or by your lifestyle? I'm not sure on the answer to that question. I know of a family friend who lives a healthy lifestyle yet she still has high cholesterol. When I was still single, I exercised because I wanted to be attractive to the opposite sex. Nowadays, I exercise because I want to live longer for my family. I walk and walk and walk without going anywhere. We have a treadmill in the basement and I'm glad it's not being used as a clothes hanger. I wish we have more space down there so we can get an elliptical machine. I'm not wishing to be skinny because that will never happen. My body type is not a stick, rather it's a rock. A medium-sized rock. :o)
