I would agree. The saying, "Idle hands are the devils playground" can be appropriated as, "An idle mind is the fertile soil of the depressed."
Although the reality is the mind is anything but idle for those predisposed to depression. The rumination, negative thought patterns and self-critical thoughts are worse than a prison sentence of solitary confinement.
For those who may not understand this, imagine standing over a 5 year old constantly berating them, in a horrifically negative way, for every action they take, good or bad. Now imagine the effects of that over years or decades.
