I don't know that it's good or bad, I think it's simply a signal, like hunger or tiredness that allows us to make an informed choice about what we can do to meet the needs of our body and mind.
I completely agree with this. Boredom is an indicator. Just that. If the light turns on it indicates you have to do something about it. the question is...is it good or bad when it turns on? That depends on everyone I mean, there's not a standard for that
