<human>: Can you condense the text into three sentences or less?

Hi guys. I know this might sound dramatic but I just think it is so dangerous and frankly kind of stupid. I know not everyone wears a helmet when they ski, and honestly, I know nothing about it - have never skied before - but I'm so uncomfortable with him doing this. he used to have a motorcycle (crashed it) and he ALWAYS wore a helmet then, I don't understand how this is any different. 

I tried saying that he isn't thinking of me (aside from himself of course) in the sense that I would be devastated if anything happened to him. I know I can't prevent him from being hurt but can't he take precautions for his own safety? I don't know. Sorry guys if I sound too intense. I would love any perspective or advice; honestly, I'm open to any advice and even some reassurance that it is okay for him to do this, if it is.

He okayed this post and we will be reading answers together. He asked me to also include the fact that he's been skiing for over 15 years. I know he's really good, but I'm just so worried! Thanks guys :)
<bot>: bf won't wear a helmet on his ski trip, this totally freaks me out and I think it's dangerous - is it? Am I overreacting?
