I'm very much enjoying his memoir. If you want to hear what Oliver Sacks sounds like, there is a 10 - 20 minute interview with him in one of the latest episodes of radiolab (it's the second story)

Oliver is also on twitter (@OliverSacks). Anyone who is moved by his books should send him a tweet and let him know what he means to you.
