@Jimfrompa Thanks for the recommendation; that definitely helps. A 25-30% improvement could help keep me away from suicidal thinking. A connection between high elevation and depression has been established. The higher the town, the greater the rate of suicide. Residents of ski towns have it the worst. Salt Lake is at 4,500 feet above sea level. We’re plenty far north, but in addition to the winter darkness, but we get even less light because the 13,000 feet tall Rocky mountains block the sunrise by a couple of hours to the east, and the 13,000 foot Oquirrhs on the west side of the valley mean the sun sets a couple of hours early behind those mountains. So we have about five hours of direct light.
