@johnnynull Dangit, BBC has gone copyrightnazi on the video in that article: https://www.youtube.com/watch?v=4b71rT9fU-I
But that was an interesting read and it's of course a fascinating subject - as always with the human brain and what is genetic and what is environmentally caused. The discussion (and existing data) regarding # is however so faulty and lacking that it's not interesting for any kind of scientific purpose.
