The translation is a little weird, but understandable, the problem is that it takes you out of the story when you have to stop to analize what the translation is trying to say.
The healt system made me think, if you work on a really bad posture until late, does your healt decrease? And is there the posibity that your total health can be decreased permanently, perhaps because of a sikness that weakens your body?
There is also the posibility that there are hidden healt points, because the bar only measures percentage, so maybe someone really strong could have 1000 healt points and 50% of that woud be 500, whilst somenone really weak could have 10 health points and 50% of that would be 5.
