What would you talk about?
First thing I'd want to ask is; Are you a cat or a dog person? (I'd want to humanize him basically)
Then I would ask him what music he likes, which artists etc.
I think I would then ask him....No TELL, him to eat all his vegetables and salads and supliments cause we need him here for as long as possible even if he gains the nick name Grandpa Wardly. Old people are full of wisdome anyways I think we all know that.
So what would you ask?
