It’s always good to have a “throw yourself at the floor, see if a helmet helps” post though.
If you were to land on the floor, would you prefer to have some form of protection? Even if it may strangle you on the internet, though not in real life.
If you were to risk being stabbed would you fancy a stab resistant vest, despite it being hot and sweaty?
If you were to be savaged by a beaver or somesuch, would you like beaver proof galoshers, despite someone on the internet telling you they may burst into flames?
How about if, whilst wrestling a rabid haddock, someone was to pass you a sharpened golf club. Handy, I’m sure you’ll agree…
Unlikely as these scenarios may sound, you just never know, and it pays to be prepared.
