Body

Body points are your character's health. When they are reduced to zero, your character is knocked Unconscious. When they are reduced further, your character is Dying. The floor for Body is -1. Once your character is at -1, further damage is ignored. Any healing that you receive while at -1 returns you to Unconscious (if you only healed for one) or back to health (if you're healed for two or more points).

Dying and Unconscious are fully explain in Health.
