Sunrise, sunset

Thoreau once wrote, "Really to see the sun rise or go down every day, so to relate ourselves to a universal fact, would preserve us sane forever."

I've often been tempted to offer this prescription to a patient. In many cases it seems as good a treatment as any, perhaps better than most, and with few side effects (just sleep deprivation around mid-summer.)

I also like how Thoreau doesn't split infinitives.
