I'm getting more absent minded as I age but still have a pretty good remembery if I recall correctly.
It does take longer to do anything, though, as I'll be on my way to go somewhere and realize that I forgot something, go back inside to get it, go do something else, get back outside and then remember that I forgot to do the thing I went inside to do in the first place.
Being institutionalized may turn out to be a blessing as long as they don't forget about me.
