Really the only thing I want from back when I was younger is my body.
This one gets some aches I'm not used to and puts on pounds a lot faster. Gray hair doesn't bother me. Oh, and I am waiting to get a body lift when they figure out a way to grab the top of my head, pull everything up, and snip off the top.
So.....maybe when we get in our 70's, we can all go somewhere and have a body lift and then go to Disneyland and act like little kids again!!
