Semi-realistic Regeneration and corresponding Increased Consumption

[Celti]

Since After The End introduced Long-Term Fatigue (which I've been using for a lot more than just AtE games), I've been treating (semi-)realistic Regeneration as costing 1 LFP per HP, which very handily abstracts away levels of Increased Consumption, etc. into “your body is expending lots of resources on healing, so you're tired and need to rest, eat, and drink a lot to make up for it”.

Both I and my players love the reduction in bookkeeping, etc. that this brings on while maintaining verisimilitude.
