How often do you flirt with genuine danger (extreme sports, dodgy travel, gremlin driving)?

Extreme sports come with extreme spreadsheets. Tracked over 11 years at Norway's Kjerag cliff, BASE jumping killed about 1 person per 2,317 jumps — roughly 123 times deadlier per jump than skydiving (~1 in 285,000). Across unmonitored cliffs and buildings, some estimates run as high as 1 death per 500–1,000 jumps.

Why the gap? A skydiver leaves a plane with ~60 seconds and a reserve parachute. A BASE jumper leaves a 1,000-foot cliff with one canopy and 2 to 4 seconds to fix any mistake. That's not a hobby, that's a coin flip with a very short countdown.
