This is why you should wear a halmit on a bike scooter skatebord.
Everyone should be wearing helmets
for safety.
Your head is safe from anything . If you crash you will not die.
They save your life. At the skatepark you can do big tricks and not have to worry about getting heart.
It is safe if you have a helmet on. If you hit a rock and fall off it is way safer then not having a helmet on.
