This is a tough one. I don't know what would have been different if the public figures named had lived longer. Some of what they accomplished was because they died young. They're remembered because they died. People who followed them did certain things because they died, and the world changed. I'd pick people I knew. Even then, who's to say I'd be doing any good just because I saved myself the pain of losing them once. I just don't know...

(BTW, Nic Jones lives.)
