In the last year, I've heard of Molly Sediel, Bryce Hoppel and now this Japanese guy all hurting their ribs. What gives?
Is it low bone density, rough sex, coincidence or some combination?

I'm just some hobby jogger who likes lots of sports. I'm speculating here with no empirical data:
I think the low body weight of runners, especially the lack of upper body muscle, contributes to the injuries runners suffer when they fall. If I remember correctly Filip Ingebrigtsen cracked a rib falling in some european meet where the fall looked "normal."
My hypothesis is that runners sacrifice upper body muscle strength and tone in order to have a lower body weight. This helps them become more efficient runners and makes running faster distance times easier. That sacrifice carries risks with it, which is an increased likelihood of upper body injuries. Runners may also be less "talented" at learning how to fall in ways that minimizes injury.
You see soccer players, rugby players, all sorts of other contact sports get hit with hard challenges/tackles, fall, and get up just fine. Put a runner in those challenges and they're breaking half their bones.
