The hell you on about? People do that all the time.

I’m part of a big group now that is in a pool doctors all over the US can check to see if they can find a match for people, because a friend of mine died from leukemia a long time ago. They couldn’t find a match for him, but maybe I can match with someone else someday.

BTW, gonna shamelessly plug NMDP. They do good work.
