The concept of “health” of each avatar is a key element in all online virtual worlds. In Toontown, how is “health” managed and its status displayed?

When I fight Cog the health is show on bottom left hand side, each time the Cog attack if is hit the concept, it will loss some health, depend on how strong is the Cog is.When my first time my concept complete drop to 0 they would not let you play any game and make to go back to playground for sleep to recover all the health. But this will take few second. when the health is at 1 the concept able to move faster.
