I see people about my age mountain climbing; I feel good getting my leg through my underwear without losing my balance.

I'm at that age where my mind still thinks I'm 29, my humor suggests I'm 12, while my body mostly keeps asking if I'm sure I'm not dead yet.

 You don't realize how old you are until you sit on the floor and then try to get back up.

If you can't think of a word, say "I forgot the English word for it." That way people will think you're bilingual instead of an idiot
