Aren't there only a dozen or so mountains above 8000 m? Can you really do that without supplementary oxygen? Amazing.

14 of them. The first person to climb them all did so without supplemental oxygen.

He made the first solo ascent of Mount Everest and, along with Peter Habeler, the first ascent of Everest without supplementary oxygen. He was the first person to climb all 14 eight-thousanders, doing so without supplementary oxygen. Messner was the first to cross Antarctica and Greenland with neither snowmobiles nor dog sleds and also crossed the Gobi Desert alone. He is widely considered to be the greatest mountaineer of all time.

wow, even his hair is interesting

Ok. This is the most interesting man in the world. Literally.

If you're ever in Northern Italy the Messner museum in Kronplatz is absolutely worth a visit.

Sure you can. Actually true climbers wear at all times a tight choker below 4000m to compensate excess oxygen in the air.
