Blood

 Have you ever lived in another country besides your country of birth? Would you want to?

"So wait, why can't you give blood?"

"I used to live in Germany for a year. For some reason, that makes me ineligible to donate."

"That's kinda cool, though. I didn't know you lived over there."

"Not much to tell. I was an infant, so I don't remember any of it."

"Ah, that sucks."

"Yeah, I wouldn't recommend it."
