I have a duty of care - my job puts me in a position where I have to look out for the wellbeing of someone. I have many people come into our shop and try a helmet on that's too big for them, dangerous to go out on the road And we will absolutely refuse to sell them that helmet. They get quite disappointed, but we won't let someone leave our shop with something which we feel is ill fitting. I'd rather lose a sale than doing so. At the end of the day if said person walks out of our building with a helmet which is not safe for them, and they have a fatal accident, that death is on MY hands personally as I knew if wasn't going to be good for them.
It's a similar situation here, if I know a helmet isn't right for someone due to the life it's had I have to inform them of that, if I don't and they go out and die due to this, then again that's on me personally. I don't want that. Now whether you believe I'm a "salesman" or whether you want to believe me as a genuine person informing people about safety that's your choice. All I ask is that someone without knowledge of what a motorcycle helmet does and doesn't do in the event of an accident / imppact doens't answer a question they're not educated on. Just because a persons head is not inside the helmet once it took an impact that doesn't mean the interior is not damaged, please don't advise someone that this is the case - I'm a million percent sure this is untrue. I'll give you the easiest extreme example, if you hit a helmet with a baseball bat with no head inside is the interior going to be damaged... yes of course it is, so please think about what you're advising when it comes to safety especially. This is something I in my job role take extremely seriously and don't want people advising others incorrectly.
