People romanticize this idea of going out into the wild and surviving like "surviving" just means living outdoors. Survival is shitty. There was a national geographic piece called "Alone in the Wilderness" where a guy went to the Yukon and tried to survive for 90 days. After 50 days his heart beat was so low and his mental state so poor he had to be rescued.
What do you consider to be a "wild person"? Would you bring a gun? Tools to build a shelter? Or would you go out with nothing but your knowledge and try to build everything you need? Because that would suck, and if you bring all that shit then really you just playing "wild man" and not being one, right?
It might be fun to do if you know you have a way out. One of my dad's buddies and other guys go out into the wild with minimal gear (they have certain rules but I don't remember them) and they agree to meet up in a specific numbers of days and see who "survived" the best. That sounds like a good time but that's hardly survival.
Or just spend one night in winter outdoors with nothing but the shirt on you back. That should satisfy your curiosity.
When I was about 15 I ran away to teach my parents a lesson. Being a dumbass teen I figured they would have the national guard out looking for me so I headed to the woods and hid out. It was around this time of year, not to cold (mid 40-50, but not summer either. I actually lasted about eight hours before boredom, hunger and general discomfort drove me back home.
My dad didn't do shit. Didn't look for me, didn't yell or kick my ass. He just told me next to be sure that's what I wanted to do because he would be changing the locks.
I have spent my whole life in the woods and on the water in Michigan including winter backpacking and hunting all day. Big difference between being prepared for it like camping and true unprepared roughing it.
