Currently, no matter how much your colonists fight, haul or craft they stay at same physical state, it will be logical to give vatgrown soldiers and similar type units more physical conditioning and more health (like 10 max health per skill point).
Also this skills will perfectly fit "weak" backgrounds like sicky child or similar, by defaulting it to 5 (150 health) and giving penalty to it for such backgrounds.
Same with mental conditioning (name choosen to evoid confusion) - units like vatgrown soldiers or scouts (who trained to execute orders) must have plenty of this, no matter how many dead bodies they see or how tired or hungry they are - they wont break.
Other background should have this skill at minimal, with backgrounds like "unstable butcher) locked completely.
Such units are unstable and can go rampage much easier then others.
Physical conditioning can me merged with melee and called "combat training"
