Thank you Mark for answering my question. I tried to ask my doctor the same question recently and he looked at me like I was speaking another language

As far as the surfing goes, I am so careful because I know what a risk it is. I just caught a couple waves in a empty lineup longboarding. I'm pretty comfortable with not wiping out I'm just terrified of someone hitting me. I know that it will be many years before I can handle a normal sized crowd and maybe never will again. I am now almost two years recovering with significant headaches and other symptoms so I know that no activity is really worth it ... even though it is hard to give up surfing completely.It just takes time to give something you love up.

As far as the helmets go I know that they will never completely protect me and to be honest I haven't been wearing one the last few sessions (if you could call them that) but I figure I should if I can.

On a postitive note, yesterday I saw a beautiful sunrise, a turtle and a monk seal. So nice!
