Is it possible to die standing up?

I think it is not possible. This can be proven by what the body needs to achieve 'standing up':

The first thing is that it requires muscle tone and balance, which is controlled by the brain.

Standing up also depends on the muscle fibers, of course.If the myocytes are dead, then it is not even possible for someone alive to stand since the muscles will not respond to the signals sent by the brain.

Muscle tone requires energy. Thus the circulatory system and (hence) the respiratory system must also be intact. However, these 2 systems require control from the brain as well.

From these you can see that this simple action requires the coordination of several systems: the nervous system, respiratory system and circulatory system. Sadly, when a person dies, one or more of the abovementioned systems must be damaged. Hence it is not possible to stand when already dead.

Yes it is possible to die standing up, but it isnt natural. The question is only meant to make you think about it because it is an answerable question that many people don't wonder about just like Can a bird die midflight? Sure, they can be shot but how would it happen otherwise?

Comedians have been known to die standing up. You might want to write Letterman or Leno and ask them how it feels.

well, if you get sprayed by liquid nitrogen while you're standing, then left like that for as long as it takes, you will die standing up.
Unless he means as we stand up, and it's also a possibility.

No When there is no longer life in the body it is unable to function in it's own power. Standing up would require life. With death life is gone. That is why we need to be prepared for the soul part of the bodies existence.

Yes

You could always die standing up. Like standing up for someone, or something you believe in. And if you ask me, yeah i think it's possible to die standing just in general.

no, it is not possible because even though you die standing still you will fall down. its like the saying "human come from dust and human will return to dust'
