# Description
Makes natural blood regeneration use up some hunger and thirst, and halt
completely when you are starving/dying of thirst.
This is necessary to fix two issues:
1. It being possible to feed off of your own blood, by repeatedly
drawing your blood and injecting it back with a syringe. (I actually
know a few people on floof who do that on a daily basis)
2. Hunger and thirst having no real impact on gameplay, besides giving
you a mildly annoying depression overlay when low.
This PR also slightly refactors the blood deficiency trait so that it's
no longer completely hardcoded in the bloodstream system.

# Description
With https://github.com/Simple-Station/Einstein-Engines/pull/858 (Make
Height Sliders Affect Your Bloodstream Volume) being merged, it
introduced variable blood volumes for differing sizes, whereas before
everyone had the same blood volume (300u).
Because Blood Deficiency subtracted a flat amount from the bloodstream,
it resulted in an unintended consequence where small characters died
very quickly due to blood loss, while large characters could live for
hours. This makes the blood loss amount of Blood Deficiency a
**percentage** of the entity's max blood volume, which means that the
time to become low blood is now the same regardless of blood volume.

- fix: Blood Deficiency now makes you lose a consistent percentage of
blood regardless of your blood volume, which is dictated by size. This
makes the time to low blood and death consistent for every character of
all sizes with this trait.
# Description
**Blood Deficiency** is a +2 points negative Physical trait that makes
you slowly lose blood over time. When left untreated you will die from
blood loss. Inspired by the SS13 trait of the same name.
Slash/Piercing weapons and bleeding are much more lethal against you.
The moment you start taking **any** blood loss damage, you start dying
because you can't regenerate blood. Even just two consecutive kitchen
knife stabs will make you bleed enough to die slowly unless you
immediately apply gauze.
Blood packs, iron pills (or copper for Arachnids), and gauze to stop
bleeding will help you survive with this trait.
Here's how the timeline looks for untreated blood deficiency:
- ~0-21 minutes: losing blood slowly
- ~21-31 minutes: blood level below 90%, start taking bloodloss damage
- ~31-33 minutes: critical
- ~34 minutes: death

**Trait entry**
As shown above, even just reducing the blood volume to less than 90%
means you will die a slow and painful death.

- add: Add the Blood Deficiency trait, a new negative trait that makes
you slowly lose blood over time. You must routinely receive blood loss
treatment to live, and even normally non-lethal bleeding can make you
start dying slowly.
