Climbing Kilimanjaro (one summit trek): 1 in 7,400 chance it kills you

~140 micromorts. Like 10 paragliding flights, or 14 years of office work. Measured.

Mortmeter: Worth it. The roof of Africa on non-technical trails; pay the altitude tax and bag the summit.

Assuming: A standard guided 5 to 7 day trek to the summit.

How we got this: Data comes from the Hauser autopsy study of tourist deaths on Kilimanjaro between 1996 and 2003, which recorded about 13.6 deaths per 100,000 climbers. That gives a baseline of 136 micromorts per ascent. 1 climb times 136 micromorts per climb equals 136.

What gets you: High altitude cerebral edema, High altitude pulmonary edema, Hypothermia.

Cheaper version: Taking seven or eight days rather than rushing it in five cuts acute mountain sickness risk by half.

Sources and method: how Mortmeter prices things, and the Atlas of measured risks.

More priced risks: Sharing a bottle of Flor de Pingus, Riding Polyppen at Bakken in Denmark, Eating 2 whole pizzas, Drinking a bottle of red wine, Winter bathing in the Øresund, A week of off-piste skiing, Getting LASIK eye surgery, Texting while driving on the motorway.
