Your brain (and thus, your nervous system) is not self-sustaining. It requires sleep, nutrition, exercise, stimulation, fun, and downtime to function well. It’s like one of those little digital pets that used to be so popular; as long as you tend to it, it will beep and smile when it should and generally behave well most of the time. And when you don’t tend to your brain, things like parenting become harder and you become much more likely to lose your shit.
