I hope someone can explain revives. They seemed self explanatory but are evidently not. I go in to play and I start with 10, or 9, revives. By the time I complete two of the three activities I am down to one even though I died only 2 times. I've been traveling from one to another, not encountering any foes and I see my revives drop. What gives. Someone, please explain? Thank you 8mileshigh
