We're in competition with other organisms for the same resources. "Our" bodies are just a food supply to somebody else. We die when we can't rebuild faster than we're being eaten.

Since when do you have gaseous hydrogen in water at room temperature?

So you're seriously suggesting that that reaction is the source of hydronium ions in water? I'd ask you for references if it was remotely on topic.
But it isn't. The topic is about entropy as it relates to death - i.e entropy (if there is such a thing) at the organism level, not the molecular level. I doubt that calculations of Gibbs Free Energy have much relevance.

I think the correct reaction is:
H2O + H+ -> H3O+
H2O -> OH- + H+
= 2 H2O -> H3O+ + OH-
I think you're looking at it backwards when you talk about "breaking" bonds. There's an equilibrium between neutral water molecules and ions. Bonds are constantly forming and breaking spontaneously.
There's no energy change in the population of molecules/ions - i.e. no heat flow in or out of the beaker of water. Therefore, thermodynamic calculations on whether or not a bond can "break" are irrelevant.
