may i make another suggestion, as my adults are both exhausted as i keep them on working. one way that is effective to help them get their energy up is by having them take naps (although, they only do that on their own. praise them when they do so they'll do it more often). i also believe that eating just might raise their energy but i can't yet prove it.
oh and i also have a question: what happens when your family member's energy bar goes down to 0%? do they die or what?
