What do you think about me landing on my head and cracking my helmet?
Did you end up hurting your head?
I did crack my head but just a bit.
Good thing you were wearing your helmet. Imagine how much worse it could have been.
I'm lucky that my head is harder than the helmet.
I would still recommend seeing a doctor if you believe that you have cracked your head. Not seeking medical attention for head injury could prove to be very bad in the future.
