General

The first thing that went for my fattie was anything bending over: sweeping up piles, putting on the kids' shoes, etc. Then came the stairs (putting away laundry).

Now when she bends over to put on her own shoes she sometimes breaks a sweat. 😂

Getting into small areas to fix things.
I have crawl spaces in my attic in all 4 bedrooms where I keep things stored.
I have gotten wider than the small doors leading into them so I have to squeeze in sideways.

When I was 400+ tying my shoes was very difficult so I agree with that too.
I had to sit on the couch and pull my leg up and lean in the direction of the foot to tie the shoe.
