Absolutely everything in the world can kill you

Oh Really ?

That's like saying a door can kill me, which it can't. Now if a person closes the door on my head then it kills me, but it's the person that is killing me not the door. The door is merely the instrument.

but still, they're using the door to kill you. If someone were to give you Cyanide in your drink, the poison would kill you, along with the person. The cyanide physically killed you, while the person was the one allowing the cyanide to do it's shit. In the case with the door, the door is being used to kill you, just as the cyanide was used to kill you in the other scenario. The door is still killing you, with the help of human strength and intelligence.

In the cyanide case... well I just regenerate.

nigga, are you retarded?

door is balanced on a stack of doors, stack of doors falls over. door lands on your head you're dead

In that case gravity and speed would have killed me, the door again being merely the instrument that transferred the motion that broke and/or blew up my head.

no, the door killed you.

also, the drinking too much water and the part about choking were two separate facts.

Too much water can kill you too, people still drink it.
