And 76 years old, he was 76 years old.

And he said, can I come with you to climb to Kilimanjaro in the record time you proposed?

Because this is a mountain that can be done between five and nine days.

because of acclimatization.

We cannot produce enough oxygen at those altitudes.

That's why we have to go slowly but surely so the body is able to adapt to the thinner air to produce enough oxygen inside.

It's producing more red cells.

More red blood cells, yeah.

And that is called acclimatization.

That takes five to nine days.

And then only 40% will be able to summit fully dressed because up there, it's also Arctic cold.

It's Africa, but at six kilometers, it's the wind and ice and snow.

And with half the oxygen, you don't have the fuel to create energy.

Right.

So those predicaments, they are there.

And for that five to nine days, only 40% is summiting fully dressed.

And this man, 76, he wanted to climb the Kilimanjaro within 35 hours, 35, not five to nine days, in his shorts.

That's what I said.

The people who are going to come with me in this expedition, they're going to go.

We are going to do it within 35 hours.
