If you are like me and tend to suffer from winter blues when the daylight fades away (and Brings Out the Inner Aztec Pessimism about the possible disappearance forever of the Fifth Sun), this article by Leslie Tamura in the Washington Post is a good roundup of expert advice on how to combat it – including the three light boxes I have deployed around my computer screen as a phalanx and exercise and exposure to morning light. (Plus it quotes from my old friend, World Bank senior official Keith Hansen, on how he combats the winter blues.) Query to VC readers: do you suffer from SADS and, if so, what do you do to combat it?
