Oh, and it may not have come through, but the amount you earn doing work is proportional to your current energy levels. So if you're a couch potato in the moment when you phone in some work, you make essentially nothing, but if you are active enough to have a higher energy level (which reduces food-to-fat efficiency and slows down weight gain) you'll pull in a lot more money. Trying to play without ever raising your energy above the bottommost baseline is essentially impossible.
