Sherwin Nuland, writer, former surgeon, held a very personal, emotional talk at TED about how he basically lost everything (read: his mind) and resurrected from it. Without him (then) knowing, actually, he didn’t knwo anything at all, he was on the brink of having a frontal lobe lobotomy, which would almost certainly have “cuckoo-ed” him. I know this sounds like an entry to skip. Don’t. Worth the 20 minutes.
