I used to do storage auctions when I was younger. I'd load everything myself. I'd also sell things at the swap meet and had no problem loading and unloading things and setting up and tearing down. While I was in college, I worked for a temp agency from time to time and one of the jobs was to pull logs into a pile, and the man that put me to work was shocked that I could such heavy work. Now I can't even lift a box without paying the price. It seems like many of us were, once upon a time, very active - physically.
