What is 10 micromorts equivalent to in regular life?**********
Well, it is about the risk of death, from any cause at all, of an average 30-year-old man in 4 days of their normal life, or about 1 day for a 50-year-old.
It is also roughly equivalent to the risk in the UK of a 60-mile (96km) motorbike ride, or 2,500 miles (4,000km) in a car, or having a general anaesthetic.

There is no climber alive whom Honnold admires more. Yet Caldwell echoes Anker's conservatism. "I've never tried to free-solo anything really grand," he says. "I've fallen completely unexpectedly lots of times - maybe a dozen - on relatively easy terrain, when a hold broke off or the rubber peeled off the sole of my shoe or something."
"If I'd been soloing, I'd have died."
