How to fall safely, its easy to learn and greatly reduces the danger of a fairly common type of injury.
Could you be more specific about how that's supposed to be taught?
The three things I remember from a long-ago judo class that have served me in good stead are
(1) If falling forward, roll -- that is, constrict all the muscles of my torso and neck so my head is driven towards my knees and I end up on my back.
(2) fall as flat as I can, spreading the impact out over the largest possible surface area.
(3) keep my chin tucked up against my chest while falling so my head doesn't bounce off whatever surface I strike.
Of course, these are the sorts of lessons that have to become reflexes to be worth anything. And reflexes are taught by practice.
I was looking at a discussion of what should be in a college curriculum, and as such discussions seem to go, there was a big list of things everyone should study, and some political claims about what's being offered but shouldn't be.
Instead, what do you wish you'd studied in college? What do you wish other people had studied in college? On the latter, do you think everyone should have studied it, or do you just wish more people knew about it? Approximately what percentage of people?
Of course, this doesn't have to be limited to college. People could learn the same things earlier or later.
