Where you draw the line is up to you. If you have a stroke and lose a big chunk of your brain, are you still you? If you’re reduced to an unthinking blob due to massive brain damage, is that still you?
Personally, I have trouble accepting that I’m still the same “me” that went to bed last night, when I wake up in the morning.
Wheras I’m the same ’”me” that I was a year ago. The “me” of five and ten years ago are farther from that, while the “me” I was at age 10 is probably not very close at all. I’d allow a pretty big amount of slop to exist in different copies of myself.

I suspect you act quite differently towards your future self compared to other people who will wake up tomorrow morning.
