It varies depending on where in the body the current is passing through. Less than .1mA, if it's across the heart.
It depends on the amount of current, enough current can cook the body.
Are you under the impression that water has "too much resistance" to electrical current? If so, I can't really explain this to you. The biggest substance one could point to in the human body is water. It's almost literally what a human body is made of. For this reason, human bodies conduct electricity extremely well. You're right to mention current instead of voltage. High voltage will stun you, but a few milliamps of current across your heart could easily kill you.
there is no krypton in the human body
No, metal is generally more conductive than the human body. Metals such as copper and aluminum have much higher conductivity compared to the human body, which means they can more easily carry electric current.
