Sorry, I can't tell if you're serious?

Can you confirm?

He looks authentic. You’d be surprised how varied and ridiculous people’s ideas about how the world works can get when they have some intelligence, some ignorance, and a little bit too much self confidence. Doesn’t seem harmful to anybody else in his case. I’ve done (and still do) my own share of biohacking.

Random threads here will ocassionally surface these guys in the extremes.

He's currently high on breathing and hallucinating a bit, don't worry too much.

100% serious. Also using similar methods, I can withstand cold 0 celsious for several hours and just sit on a computer and read, wearing just shorts nothing else. Nowadays though, getting older, it starts to be a little bit challenging.

Some years back, I sat in freezing cold, 12 hours a day, wearing almost nothing and just reading. The more I can withstand cold, the better my eyes work.
