How old is being 'old'?

Written by Luthor Dorr for the Union-Times on
How often have you heard someone say, or perhaps had this statement directed at you: "You're only as old as you feel." 

They might really think that or they might be trying to make you feel good if you look tired after mowing a tiny lawn, or shoveling for only five minutes.

I remember a few years back when someone said that to me and my answer was: "Yes, but I can't physically do the things I could do just a few years ago."
Now, it turns out, if a recent survey is even close to being accurate, 57 is when you're old. I take issue with that.
