Light

Ironically my post last night was about sleep because between 'spring forward' and my nervous anticipation of teaching a lesson I woke up just after midnight and couldn't get to sleep.  I ended up working at my computer for several hours on a task I didn't need to address.  I have been studying the benefits of light, which along with salt and animal fats have become demonized by the conventional medical establishment.  I plan to walk at least a quarter of an hour a day in dawn or twilight, unless it is really overcast or precipitation.  Light is a lovely thing in proper dosage.  I am grateful for light.
