[General, Gaming] How would you Quantify 1HP? What would a 10HP injury be?

Also, How much HP does the average person have?
Does it depend on weight, height, gender?

How would you class illnesses? What would the 'statistical' effects of some diseases be?

What would a 5, 10, 20, 50HP injury be? On the flip-side, how much statistical damage would a broken arm be? or a punch in the face?

How long does it take for my be to regenerate 1HP?

It's relative to the total scale. A 10hp injury for someone with 1000hp is going to be bruise. For someone with 10,000 hp, it's barely a love-tap. For someone with 50hp it's going to be a serious laceration. 

HP is an abstract representation of general physical wellness. Its going to cover everything from serious injuries, to fatigue stress, to temporary shock. And these sorts of injuries are present across the board, regardless of size or durability. Because of this, trying to apply any sort of standardised representation of the types of injuries X points represent is going to be impossible. 

Similarly, regeneration is difficult to account for, because it's going to depend on the same thing. A 1000hp entity is going to be able so shake off 1hp of damage in a few minutes, tops (most likely in seconds) but for a 10hp entity it could amount to a wound that would take several weeks to fully heal. 

Generally speaking though, most systems have entities falling unconscious at 0hp, not dying outright. This indicates that the majority of damage sustained in not inherently life threatening, so even if you take a 50hp hit, it's unlikely to be anything like amputating a limb.
