really really hard
The brain is soft tissue enclosed in hard bone, the skull. When the head is hit with force, it cuases the brain to hit the skull causing a "bruise' or concussion.
When you are hit hard enough in the head the your brain moves in the skull and hit the side
There is no life span on a human skull. You can only brake it if you fall really hard but then you would most likely die and you would be parilized if you did not die.
you would most likely die.
A skull on a pvp world means that you got hit and ran or hit and ran. Having a skull makes it so when you die you lose all your items. There is no way to get rid of it, except if you die. I would suggest putting all your items in the bank except for a weak weapon and go and try to kill a weaker player. When you die your skull should disapear. You should watch out if someone is attacking you before you leave. If you attack them back you will not get it.
The skull can protect the brain, scientifically.But, it's better to take procautions to help protect it even more.
you will have a canser and die
It obviously depends on how hard you are hit.
they both are as strong but if you hit them too hard they could break i like brisk
yes if you hit the scull so hard it could be cracked
not very
because skull protects it, skull is a hard bone to protect our sensitive parts like, brain, face.
