Forget Xavier's School for the Gifted - marvel instead at the real life superheroes on the roof of the world.

For years anecdotes circulated amongst climbers, of the superhuman ability of the Sherpa to function at high altitude, when all others succumbed to mountain sickness - or worse. Now science has shown how they have evolved to live in one of the most inhospitable environments on Earth.

Thousands of years living in the thin air of the Himalayan plateau has given the Sherpa biology that differs from lowlanders from the very cellular level.

Much of the Sherpa science in this video comes from the Xtreme Everest team who are doing great work at high altitude to help sick patients (in normal sea-level hospitals!) https://www.xtreme-everest.co.uk/

Tashi Sherpa kindly got in touch to tell me he is the superhuman carrying that massive load at 00:03:35. His channel is here:    / @tashisherpa3633

It's hard to express how much I love Nepal, please consider visiting responsibly or donating. The 2015 Earthquake killed 9000 and displaced many more. Whilst climbing brings in a lot of money to the Nepalese economy, the government are complicit in the exploitation of Sherpa guides.
