I just turned 40 in May fyi...
The thing that PISSES me off if I had to pull my fridge and go down THREE concrete steps to my patio to defrost it and clean the coil last night . I pulled and pulled on this thing this morning trying to get it back up ONE step and couldn't budge it. My dad lives next door and is a disabled vet, my wife has bad scoliosis so no dice there. All the while I am wearing my knee brace from a torn ACL (other knee not the same one from 10 years ago). I also have arthritis in my lower spine. So I have to call my neighbor down the road to help me push it up the steps while I pull the dolly. This is a bunch of horseSH**! 15 years ago I would have toted that thing on my back and certainly wouldn't have needed help along with a hand truck.
WTH happened to being 25 and bulletproof??
It only get's worse. There will be a day that you wish you were 40 again, believe it or not.
