Has anyone else listened to any of these? they are on iplayer i think. I was interested most in the programme about splitting twins up at school, but it was all quite interesting. A lot of the twins said they got a lot of interest and questions because they were twins, which is what i find also (and mine aren't even identical!).
and i was interested to find out the high incidence of homosexuality in twins (seemed much higher than in the general population).
