Morning person? Night owl? Something in between? When are you at your best? I’ve found that no matter the hour of day, I am the best me I can be after a good nights’ sleep. Sleep a wonderful state of unconsciounsness after shopping at the mall with a four year, a five year old, a six year old, and a 7 year old. Let’s face it for some of us sleep is a luxury, better than a day at the spa, but the reasoning behind sleep and the various disorders, damages and wonders it can cause are a mystery to even the brightest scientific minds.
