Having recently fallen off my bike and ending up in hospital with a bleed on the brain and fractured cheekbone, I am so glad I was wearing my bone dome.

It made me think about those who don't/refuse to wear one and I am genuinely interested as to why.

This is not meant to be a thread advocating the use or otherwise, but more to try and understand why you wouldn't and, perhaps more crucially, what would make you change your mind.
