What potential uses do you see for our Hard Hood?

We have our own ideas on the potential uses of hard hood, such as toddlers learning to walk, active kids and teenagers at risk of banging their heads, kids going through a head-banging phase (normally linked to food intolerances), adults doing DIY tasks, skilled tradesmen, sailing, skiing, skateboarding, ripsticking.
But we really need your help to try to get other activities where people are at risk of minor head impacts and abrasions, but where the law does not require the user to use a hard hat or cycle helmet.
