Thanks, yeah fortunately I do take walks out to the garden usually at least once a day. Lately we've been getting hit with those hurricanes (up in Boston, so no damage, just lots of rain and wind), so I haven't been out as much.
Speaking of autumn depression (here we call it Seasonal Affective Disorder, or "SAD" which is a somewhat amusing acronym, not so much while I'm experiencing it), I have a "happy light" which is right next to my desk, I should start using it now that the days are getting shorter.
