Ramblings on Hitpoints and thinking the other atributes of the character sheet as modifiers

"Combat is messy."
                      -James Young, 2018


After reading the linked article I got myself thinking on combat, more importantly: Hitpoints.
When I run my games I go to the "Don't get hit points" line of thinking, that is: getting to zero HP doesn't mean death, uncounciouness or whatever, it means your character has become open to FUN and JOY.

See? Character development!

So HP ends up being an abstraction of your character's readiness in combat, how they react and deal with the chaos of violence, in other words HP is a measure of the character's attetion/adrenaline/fight-or-flight response. If so, then why only the CON modifier is added to your total hitpoints?

Combat is a messy ordeal, so are other adventuring hazards and they change your character's reactions to the world. That's why catching a breather is so vital and also that's why PC's are willing to break out a fire and eat something in the middle of an expedition to some forgotten hole. They need to get their shit together. And ny getting their shit together I mean their whole shit not only their physical hardiness.


Enough rambling, on with the crunch:
The system:

When rolling your HP instead of adding only your CON modifier add ALL your abilities modifiers and then roll the character's HD.
Now the hit points act as a clearer translation of the character's abilities, maybe the fighter is a hardy fellow and has litle problem chugging massives quantities of booze and even some poisons, but the light upstairs is a little dim and he ends up not being so good at getting out of harm's way. Meanwhile the scrawny magic-user has a domeneering presence which makes her enemies flinch ever so sightly when aiming at her, and so on and so forth.
