Help Needed: Health concepts in games

GB Community, I need your expertise and help.


First of all, what would you call the feature in games where there is no HUD or numerical health bar? 


Visualized health? Contectual health?  I searched around the database and found nothing.




Second, and this is more fun, what are some of the best and worst examples of the implementation?


For worst, I am thinking Jurassic Park with the cleavage tattoo, or MW2's jam sandwich screen indicator.  Nonetheless, I am sure some better examples are out there, and I know you guys and gals know them.


Also, are there any best examples?
