When the apocalypse happens I'll make sure to grab the only book I'll need the SAS Survival Handbook gifted to me the the great Quothetheraven79. It teaches all you need to know in all different climates. It's also in color so I know what mushrooms will kill me and not make me feel good. :) If civilization falls one thing I wish for is to meet up with Quothetheraven79 so the book of survival can spread it's wisdom to the one that gave me the knowlege.
