Incredibly easy to read, long, self-effacing, nonscientific, entirely unmemorable and strangely without laughs for a native born Brit.
I won't give anything away if I mention the only three sentences I remember after so many years: 1) He studied biology originally 2) He wrote cheat sheets -- or was it essays -- for students after he graduated 3) The only funny moment is his only real anecdote, where he gave a speech calling Jesus Christ an "itinerant preacher" and called the house down on himself.
Another example suggesting that authors seldom have adventurous lives but are the only ones keeping a record.
