Legendary Survival Overhaul /Thirst, Temperature and First Aid

Adding the "Legendary Survival Overhaul" mod would add a thirst, temperature, and heart rate system to Minecraft, and this mod does that job very well. Health would regenerate naturally, not necessarily when hunger and saturation are full, but gradually, similar to how it was before. Using bandages would repair damaged limbs and provide a regeneration buff. It makes more sense to use a bandage in the middle of a fight than simply eating a steak.
