Not sayin' one shouldn't, but that cannot possibly be the reason I'll wear one: I jump neither that high, nor can I do triples.
Going to go the negative in this instance, but what's with the last sentence asking for donations to his facebook page to help with medical bills. Should maybe take travel insurance or some form of cover or even consider chances of injury when doing big moves like this. Good on him for doing big moves and pushing the envelop, but at what stage does a person take their own actions and hence consequences and foot their own bills in due course.
I don't see every sports person whether professional or not asking for handouts every time they end up in hospital.
A lad at newport reef on Saturday smacked himself up pretty badly - looked like a really bad cut to his face and was taken to hospital. It made me decide that the Gath was going to be used.
Hopefully it's superficial and heals quickly.
Original post: "The reason WE should wear a helmet"
Hockey Players used to not wear helmets - now goalies have throat guards.
Seat belts are mandatory in many places in North America.
If you are not falling in, you are not trying new stuff.
I used to not wear life jacket. Do now in deeper waters - hate to be under the sail.
The pros fall in - this case is an example - have seen Micah Buzanis, Jem Hall et al fall
Last summer i fell in the water after hitting the sand and hit my head on the bottom. I came out of the water all dizzy. The same day my w/s buddy hit his head with his mast and was walking about with an egg on his forehead for one week. Next week i purchased a helmet. I have a big head and HATE hats n helmets. Now wear a helmet in the bigger winds 7-oh and down. If accidents are avoided perhaps it will not become mandatory !!! I prefer to have the option - light air cruising - no helmet nor jacket :-)
safe sailing y'all

Apart from the protection...
I thought it would be a nuisance, but have found that the sea water doesn't go into my eyes when I wear a helmet. With the retractable visor it works better than the sunglasses, and the visor also protects me from the spray in the chop.
On the downsize, it gets noisy inside when sailing up-wind.
Funny though, when I wear it I seem to hit the boom and mast a bit more with my head. Or is it just louder? 
Wear a helmet, has saved my life, I dont understand why other sailors dont wear them, they cost bugger all and once you get used to them they are no trouble to wear. So if you cant decide, just go an buy one.
Stops sunburn on my bald dome. I always wear my gath for safety reasons except when lightwind cruising.
Where do you draw the line with the protective equipment. Those guys are doing crazy moves every day of the year and you never hear of anyone drowning or being really badly hurt. That usually means that the odds of being hurt badly are quite slim, so as a result the protective gear can be omitted.
I did however used to wear a helmet when I windsurfed in the late eighties. It was bright pink! 
What was I thinking
I started wearing a helmet to reduce swimmers ear when I was learning. That worked.
As I progressed to waves, it seemed a good idea.
I've had a few nasty cracks on the noggin, usually while trying to tack in light air, and was always glad I was wearing a lid when I heard the bang.
15 years later, I am exceedingly grateful for the sun protection it gave me. My face, head and ears are unscathed despite many hot days on the water. I know for a fact I would have had sun cancer cut off my face without it. My scabby arms are the evidence.
A recent forward loop attempt ended with a solid smack on the side of my face, easily hard enough to burst an eardrum, but again, old Gathy was there to rescue me.
I champion anyone's right to not wear a helmet windsurfing (or to choose when to wear one on a pushy too), but for me, the advantages far outweigh any issues.
