Tongue rolling

I had a go at rolling my tongue today. Mummy and Daddy can both do it so according to genetics I should be able to do it as well ... unfortunately my tongue doesn't know that yet!

"At bottom every man knows well enough that he is a unique being, only once on this earth; and by no extraordinary chance will such a marvelously picturesque piece of diversity in unity as he is, ever be put together a second time."
(Friedrich Nietzsche)
