A person in this document is either a player or a bot. A person should have lots of stats and abilities. A couple of stats:

• Health
• Hand-Eye coordination: used in aiming, noticing,...
• Strength
• Physical Shape (aka condition)
• Weapon skills (mostly per type weapon)

All these stats are not numbers, they are localized to a part of the body. and they are not seen, except some in special places. the idea is that with training you can improve those skills, and at first, you won't notice em, but after some training you can see the results gradually, and there should be no limit to those stats, so that in time your character can allways be better. but training wouldn't be training without the much needed rest. the harder you train the more health you lose, but also you'll gain more strength and when you rest, you heal and then you'll see the effect much more.
