I’m thinking that it would be more realistic if you just randomly every now and then cause yourself a small amount of damage while performing some task, and if performing tasks took longer(or were impossible) with injuries.
While butchering, there should be a small chance to accidentally slip and cut yourself (with the chance inversely proportionate to the butchering level of your tool and your survival/cutting levels), or to stumble and whang your knee. etc, the chances should be increased depending on your current damage levels.
in addition to all that, i feel like trying to do things like tailoring with massive trauma to any part of your body( but in particular your arms) should take 2 to 3 times as long.
if you had just been opened up on by a turret in RL, you wouldn’t just go hone, slap on some bandages and start sewing up the holes in your trenchcoat like nothing had happened.
One last idea is that scarring and permanent damage should be a thing. if you get your arm crippled, you should suffer a permanent dexterity or strength loss. or perhaps random flareups of pain from ‘your old ________ injury’ which causes pain at a minimum.
