David - I learned the weight equivalents after DaVinci when I tried to pick up the smallest pack of applesauce they had at Sam's - stopped me dead in my tracks. Turned out it was 4.8 pounds. Had to ask the girl passing by to put it in my cart.
At 56, I actually had to ask for help with my stuff to the car at the store. Then once home, had to get my neighbor to help carry the stuff upstairs.
ED is kid's stuff damage to one's morale in comparison to what I suffered that day.
Needless to mention I was shopping for applesauce - my morale was in the same ditch as my bowels.
