1. how can you use this as an argument? that completely varies person to person, and you're completely ignoring the protection that helmets provide.
2. they've also been proven to provide substantial brain protection at much higher speeds, reducing the potential of brain injury by between 70 and 85% depending on the study.
3. for the * you should have put at the bottom *if you wear a full face helmet, in which case the impact danger is probably much higher and so the protection becomes paramount. the average helmet suggested absolutely does not limit visibility, especially if you're already wearing goggles (which you are, don't lie to me).
4. as long as you're alert and know what's going on around you, this should not be a problem, and again, substantial amount of protection is provided on the off chance some silent skier bowls you over.
5. i'm sure i could find a study finding just as many neck injuries occurring in crashes without helmets, and a lot more brain injuries.
6/7 under normal skiing circumstances these odds decrease as your skiing level decreases, but for, you know, a freestyle skier, the risks you take are far, far greater. even if you're an amazing skier, when you're throwing inverts, hucking cliffs and ripping through trees, your risk of a tbi dramatically INCREASE, prove me wrong on that.
sorry bro, but this just weak rationalization. when it comes down to it, wearing a helmet is the smartest option. just like all the naysayers for helmets, i don't wear mine all the time because sometimes i don't feel like it, and i have confidence in my ability as a skier, but that doesn't mean its a good idea. helmets protect your head from brain injury in a high speed, high risk sport, that's all you really need to know.
