No. Ive had fall technique trigger in accidents I did not see coming - including literally having a ladder yanked out from under me, but that was after over 3 years of 2-3 times week judo and jujitsu. Martial arts, however do have one major selling point. As exercise goes, a good dojo is simply a lot of fun. This makes it much, much easier to keep up than a gym subscription. Milage may vary for people who do not enjoy being tossed around as much as I do. I do emphasize "good". Quality of teaching and social atmosphere vary very widely. If you want to do this, make sure whereever you go has a tone you are comfortable with, and that their teachings has some sort of reality benchmark related to why you go. If you want to do it as a sport, try to find a dojo that has people in it that win contests. If you want selfdefence, the one the police use for qualifying training ought to be good (.. if your local police force is at all competent) but taking up parkour is probably more useful.
Diana Hsieh interviews Dr. Doug McGuff about avoidable injuries and deaths.
He's an emergency room physician in South Carolina, so he's pretty much just talking about what he's seen-- different regions have different characteristic injuries.
He says that you're safest in the largest car you can afford, which raises some interesting ethical issues.
There's a fair amount about the risks of getting overfocused on getting something done. This adds tremendously to the hazards of using ladders.
Also, did you know trees can go sproing? One of hazards of chainsaws is that a good bit of energy might be stored in a twisted tree trunk. Don't just know your physics, apply it!
More generally, there are machines and situations (ATVs, chainsaws, airplanes, skiing, etc.) which tend to make people feel more competent than they are.
On the other hand, injuries from rock climbing and horseback riding are less common than you might think. I don't know why the ancestral environment didn't give people a reflexive distaste against diving into water. Perhaps people back then had too much sense to dive much.
One of the pieces of advice-- to get out of stressful relationships-- is too general. This is mostly a good idea, but from what I've read, leaving a violent relationship can lead to more risk of violence. It's still a good idea to leave, but it's important to leave cautiously.
Both McGuff and Hsieh are objectivists, so some of the discussion might be in mind-killer territory.
Edited to add: It's possible that objectivism would be better discussed under a new post. It's certain that there's a bunch of interesting material in the podcast, and avoidable accidents are worth discussing.
