It’s fascinating that human beings are able to climb every single mountain on earth without supplemental oxygen.
Think about that for a second.
Mount Everest is 29,032 feet. In comparison, Olympus Mons on Mars, the largest/tallest mountain in our solar system, is 69,648 feet.
It makes me think we have evolved to be able to handle any challenge that may come our way here.
