I spent a summer regularly exercising with a group of friends who were all in the 50-80 age range (and they kicked my butt). One day there was a conversation like this:<p>&quot;You know who I saw the other day? Nancy!&quot;<p>&quot;How&#x27;s she doing?&quot;<p>&quot;Well, she&#x27;s OLD&quot;<p>&quot;Yeah, that happens&quot;<p>&quot;How does that happen anyway? One day they&#x27;re your friend, the next they&#x27;re old and only complain about their health&quot;<p>&quot;It&#x27;s because they stop hanging out with young people&quot;.
