After reading Finding Manana, I've been interested in Cuba, so I'm reading Che Guevara: A Revolutionary Life by Jon Lee Anderson, which I have had for a few years but hadn't gotten around to. It is thorough: excluding the appendix, notes and bibliography -- 754 pages. Fortunately, there's a lot of context about Latin American politics and economics, so it's more than just a recount of one man's life. But this is no way to get ahead on the reading list.
So, your Che fact of the day: He had bad asthma.
