Fortunately, it turns out that I can survive without chocolate, so I don't go insane and nothing else happens.

The next user is floating in the center of an intergalactic void. There is nothing within a 500 million light year radius, you cannot teleport, your spacecraft has no fuel, and there is absolutely no rescue.

I cannot teleport, but supplies can. I remain there alone but safe as I wait for a rescue craft to come pick me up.

The next user spontaneously combusts.

I am trapped on Venus in the future, when it was colonized and terraformed.

The next user is suddenly teleported to the center of the Milky Way's super massive black hole.

With low speed so it doesn't hurt.

The next user is a mortal human that drinks mercury.

I drink one yg (yoctogram) of mercury.

That is far less than one atom so I am unaffected.

The next player is falling into a black hole with real life physics and no immortality/robot/ultra spaceship. He has just crossed the event horizon.

The black hole happens to be a wormhole. I am not immortal but have a super-strength suit that can survive the insane gravity. The wormhole takes me to my base.

The next user is halfway through a wormhole, when it suddenly destabilizes and the user is ripped in half. You are not immortal, this is real life with real life physics, it is the present day, and you are a regular, naked human with nothing.
