On every mountain lie a bunch of extremely fit, strong and motivated corpses.

I honestly don’t get why people try to climb without supplemental oxygen before they have climbed it with supplemental oxygen.

As a Nigerian, I’m deeply sad to see his outcome. But huge props to my Kenyan brother for striving for greatness in this marathon we call life.

Basically the human body is not made to cope with / survive Everest

What a shame. I'm sure he would have made it he had he used oxygen.....and it would have been such a defining moment for him and all Africans.

I feel like I could summit Everest without oxygen. But I’m also a fool

Climbing this mountain without supplemental oxygen is a death wish.

If you’re going to Everest to prove a point, don’t go to Everest.

No oxygen is the same as swimming while holding breath. You only have a very limited of time

Kirui’s family is truly amazing and full of such grace.

Impressed these comments aren’t toxic as I expected. Probably nice moderation

can you imagine your hands and feet frozen and you still have 6 hours to go

That hiking company did him dirty for giving him an inexperienced sherpa.

You all didn't watch the whole video. The man was sent up there with a novice sherpa who was not equipped with the knowledge to lead this type of expedition.

Come on now my brotha, this is NOT what we do. No oxygen? Climbing Everest?

Always have a backup plan ALWAYS

Kalejins are wonderful people. They have a genuinely humble disposition, you go to eldoret and you'll meet world record holders walking around in the streets like they have done nothing. Very humble humans.

Rest easy brother

Absolute stupidity, walking without oxygen cost him his life.

A lot of comments focusing on the hubris of the climber but not the dishonesty of the sherpa who was not honest with disclosing his lack of qualification (the company was dishonest first, yes, but the sherpa also should have realized the risk when informed of what kind of expedition this was) It very well could have been the case the climber could have succeeded or at least failed and made it back safely had he gone with a qualified sherpa, or if he had perished, it would 100% be his hubris without a doubt
