If you really need this to be realistic then You would be permanently killed by the first enemy that hits you. Not many would survive a fireball let alone just an arrow.
Real physics is thrown out the window with a game and I don't think really should be compared unless you want to play a simulator.
Now you're going into the stupidity section. Please leave it.
There is a 100% difference between visual reality and physics reality, and please understand the difference between them before you post next time.
