In the "you learn something every day" column, please add the factoid that the human liver is able to regrow a substantial part of itself. I find this incredibly odd. I found out from a friend whose relative recently had a large part of her liver removed. Apparently transplanted livers will also regenerate in the host's body, so in theory one liver could be split and donated to two hosts with each side regenerating to about 80% original size.
