The old DRLP website has gone down. It has been replaced by dfprofiler.com. Students can get precise information on their hunger and health condition here.
For example, when your monitor in Dead Frontier says that you are "Nourished" or "Healthy," DPProfiler may reveal your Hunger is at 80% (meaning you can imbibe a whiskey) or your Health is at 88% (meaning you can take a Steroid).
Thus you can avoid wasting food and meds, not taking them when your Hunger or Health is at 99%, for example.
