I really enjoy this show. In my opinion is the best survival show by far, or at least the one that better aligned with my experience and way of seeing the world.
I loved the Amazon episode and can personally corroborate how scary is to look eye to eye a 90 kilos cat. In my case it was no in the jungle but in the steppes but nevertheless very, very, very (need fresh underwear) scary.
Is a down to the earth, worth to watch show.
And by the way understand his wife and body complaints, really do.
Best Regards
