According to a few bios out on the net, Boris was born in 1938 - that would make him nearly 70. There is NO WAY he's 70!? I remember a thread several months ago about their birthdays but don't recall how old they are. Anyone know? This link is one bio, for example. Their date's of birth are mentioned in paragraph 1.
