Seriously, aside from the folks with the “2hrs of sleep is enough” gene, it’s not. It’s an actively harmful myth that is sold hard. Start gathering your own evidence, with a critical fact-finding eye. Don’t just accept the narrative. It’s one of those legitimizing stories that serves the teller.

Try watching The Dawn Wall or Free Solo, keep notes, and fill in the blanks on how long they were gone from family. It’s a canned example of how it gets glossed over.

The same attitude as towards gear in weightlifting is appropriate. They tell you it’s natty all day long, but you know delts don’t get that round without gear.

Yeah I think that word is spelled i-m-p-o-s-s-i-b-l-e.
