Two of a series of short and interesting videos.
This first one deals with the brain. It's amazing to think that until quite recently they didn't know what it was for.
This one deals with the notion of Golden Ages - something very many people seem to take very seriously. A few years ago in a pub I reckoned that this was the best era yet for "mankind" I was roundly attacked and regaled with tales of parents idyllic lives pre-1950's. For me it sounded like ignorance was indeed bliss.
