ca. 15 minutes long. I follow this youtube channel constantly, it's very interesting, he has some wonderful explanations for all sorts of things, give you nice pools of scientific knowledge, whether you want to know about "why do we kiss?" or "how much money is there on Earth" or "Why do we wear clothes?". Most of his videos are shorter than this one.

When do you feel nostalgic?

PSSST: found another interesting video relating to this forum: http://www.youtube.com/watch?v=qjfaoe847qQ, "what is consciousness?"

Interesting. Except for the grammatical tick that's stuck to everyone nowadays, he didn't annoy me at all. That's rare in a Youtube lecture - really, any kind of lecture. Good presentation; excellent organization of the material; just enough science; well paced; a large subject covered adequately in a short time.
