Interesting video, thanks.
Though I'm not sure of the validity of comparing the risk for stroke over a lifetime, with the risk of pregnancy on a single intercourse. Seems to me most women do get pregnant at one point or the other, and sometimes many times
Aside from the numbers, I think there may be a psychological bias also in how we perceive risks we can't do much or anything about (like stroke or nuclear conflict) compared to those we get to decide about taking or not (breeding). And another one in discrete occasions versus more continuous exposure: I may well get cancer from smoking, but I cant say THIS cigarette I'm about to smoke will be the one to start my cancer. But it could be THIS guy I'm about fuck who knocks me.
