Helmets don't prevent rotational forces. You have no idea what would have happened. There's no science behind what you're saying. People die/suffer tbi's all the time with helmets on. Blood is actually irrelevant. It just makes it "look" bad. It's the unseen damage that's happening inside your skull as your brain slams around that is the problem.
I'm NOT against helmets. Just saying their value is exaggerated by people who don't understand that most of the damage including fatal damage takes place from the brain slamming inside the skull suddenly.(ie a concussion) Think of an egg. You can protect the shell all you want, but that yolk is still going to get damaged from the sudden violent shaking. A helmet's main thing is to prevent skull fracture. For example landing on a curb with the back of you head. A helmet will help with sharp impacts like if someone hit you over the head with a hockey stick. Landing on your head on the snow is much different type of injury and a helmet will have little benefit. Just the way it would have little benefit if you are punched you in the chin. Rotational force.
Therefore, I don't think people should be FORCED to wear helmets. If you choose to wear one than that is your decision. I'm not saying they have no value. They do, but certainly not enough to call someone an idiot for not wearing one for example. Their benefit is limited in skiing. Especially if you're not skiing very fast and avoiding the terrain park. A helmet is of enormous benefit in the terrain park. But the terrain park is a dangerous place. You would be safer with NO helmet just cruising trails than wearing a helmet and being in a terrain park. A helmet is also of benefit if you're skiing tight tree's like on the east coast. But then again running into a tree with your head is a really bad. If you're that worried and think people should be forced to wear helmets, I'd just avoid tree skiing, not add a helmet and think you're good to go.
It really depends on what you're doing. Skiing a wide open trail at slower speeds? A helmet has little benefit.
If you CHOOSE to wear a helmet that is totally fine! My only issue and the point of this thread was that it's ridiculous to force adults to wear one.
