I haven't shoved oven mitts into the fridge yet, but there's still time; I'm only 69.
I have walked into a room & immediately forgotten what I needed to get.
I've learned to go through the kitchen & write a list before shopping; otherwise I forget to get things or buy more of something that I already have too much of.
A couple of times, I saw a famous actor on TV whose name I've known for over 50 years & said many times, but couldn't remember for several minutes.
When my mom was 78, she couldn't find her bridge. She called me, panicking because she couldn't eat without it because it was almost a full upper denture. I found it in the kitchen trash.
My sister (who was 50 at the time), lost her keys & asked me to help her look for them. After not finding them for 30 minutes, I said, "I'm going to look in a weird place." When my sister saw me looking through the trash, she said, "Aw, come on....you really think I'd be stupid enough to throw my keys away?"
I said, "You might have had your keys in one hand & some trash in your other hand & just threw the wrong thing away."
HAHA - I found her keys in the trash.
