What old person thing did you think wasn't going to affect you until it does?

Memory issues, here. I didn't think I would have bad memory issues until just a while ago, I had a thought on the tip of my nose, but forgot it in seconds and how it took me minutes to recall it. That's a key sign right there.

Some people have better memory in old age, like it's unreal sometimes with what some of them can remember. While the average person forgets thoughts in moments.
