I heard an excerpt from one of his books on NPR a few years ago, & knew at once that I needed to read that book. As is my won’t I bought all three of his then published books at the same time. Here they are:
I learnt a lot from his ‘The Disappearing Spoon‘ — which was the first one I chose to read. Until I read it in the book I had never heard of ‘Argyria‘ (i.e., permanently turning blue from ingesting too much silver) or how our brains need iodine in order to function satisfactorily.
So now I have learnt about ‘synesthesia‘, i.e., when one sense invokes another, e.g., seeing different colors when they hear noise. Franz Liszt (1811 — 1886), the Hungarian composer, had synesthesia. He was as such a synesthete. But, there are lots of other forms. Some might see colored shapes floating around them while having sex.
Wikipedia as a fairly decent article about it. Start there if you are interested — & you should be.
LSD, I also learnt, invokes temporary synesthesia! Didn’t, of course, know that either.
