Not sure why you're being downvoted, I can attest to this. There's only a certain amount of care you can give at a steady state (though, this does _seem_ to be able to increase, like a muscle at least for me personally). That said, if I work it too hard for too long with too much stress I experience burnout. Burnout, as mentioned many many times by people far more eloquent than I, has different levels. Can be mild, can be major malfunction.
