Hank: An important thing, when life begins, is to keep outside out and inside in.  That's really almost the whole basis of a little thing we call homeostasis. There's a border between living and dead, between what you see and the eyes in your head.

The largest organ you have in your body, yet if-[laugh]

The largest organ you have in your body, yet if I can see the whole thing, it's a little bit naughty.

H: There's not a lot that rhymes with 'meters'. And I wanted to talk a little bit about the sort of specifications of our topic for the week which is skin.

S: Sure, important.
