We’ve been binge watching the survival series “ALONE”. several contestants drop out from constipation when they have to resort to eating bugs and wood fibers.
And a good way to learn how lack of proper food will kill you very fast.
Those people who blithely babble about how "you can live three weeks without food so don't worry about it" have never been in a survival situation. When your muscles are shaky and cramping and your brain is foggy you are going to die. And that happens long before three weeks.
And others for drinking water when a bear has just relieved itself upstream
Bugs should be no problem, simply crunchy protein.
Wood fibers? What, you think vegan is a survival strategy?
As to the ollllld dude, perhaps he forgot to chew and the little buggers grabbed hold on the way down.
Natural selection. Even birds aren’t that stupid.
