Goes to show that you need to be very careful about what you read(or watch) related to survival.
I would LOVE to take bear grylls or the dummy who wrote that SAS survival handbook with me on a two week hunt. I would love to see how they make some of the stuff they preach work in the real world.
That "dummy" (John “Lofty” Wiseman) who wrote the SAS survival book has a pretty impressive
resume and background. I would spend 2 weeks learning survival skills from him...
