I was replying on a phone (and am doing so again now), and regrettably left out a few details.  First, I was replying both to your comment and to the parent comment.  Second, I have not been diagnosed with SAD, but I do have a delayed&#x2F;non-24h sleep cycle that is exacerbated by the short, cloudy, pollution-heavy winter days where I live.<p>My main objection to rsync&#x27;s comment was the flippant dismissal of people with actually diagnosed depression (&quot;not interesting&quot; were the exact words).<p>In response to your present comment, I would say that people who find themselves trying to invent solutions to their problems have likely already found the medical establisment to be less than helpful.
