Book Review: The Mind’s Eye by Oliver Sacks

Oliver Sacks' books are impressive and this one is no exception. He's always willing to go that extra mile in trying to understand the experience of people who are confronted with all kinds of neurological anomalies. One of my favourite Oliver Sacks quotes is very truthful and at the same time marvelously reveals his curious and compassionate attitude towards his patients.

I was struck by some remarks concerning long term vision problems astronauts are having.  KN: This week we've been doing a lot of experiments on our ocular health.
