I have finally been able to breathe out after an intense 4 days reading the 1959 book Endurance by Alfred Lansing. It is the story of Ernest Shackleton and his crew who set out to cross Antarctica in 1914. It is amazing how much time you can squeeze out of odd moments of a busy day to read if you are determined to do so.
I do not want to spoil it. All I want to say is that I am confident it is the greatest real adventure ever. Perhaps it will become the greatest there will ever be. When humans explore space maybe there will be similar adventures. The Martian by Andy Weir and the film Gravity come to mind, but I think both stories are more probable than Shackleton’s, and they are fictional.
