The Pope has it but he does not use it. Your father has it but your mother uses it. Nuns do not need it. Your lady friend's husband has it and she uses it. What is it?
I do not breathe, but I run and jump.
I do not eat, but I swim and stretch.
I do not drink, but I sleep and stand.
I do not think, but I grow and play.
I do not see, but you see me every day.
What am I?
