And you'll note that some of these are truly exceptional people, with a habit and history of doing the nigh-impossible.

Heck, if you just can't suspend belief (and I find it a bit boggling that one could swallow all of UF yet strain at this gnat), imagine that one of the subtler changes made when the universe was rewritten in 1991 was to make polygamous relationships, along with various subatomic particles, more stable. ;)
