Michael Breus (@thesleepdoctor) is a clinical psychologist, board-certified sleep specialist, and author of The Power of When: Discover Your Chronotype -- and the Best Time to Eat Lunch, Ask for a Raise, Have Sex, Write a Novel, Take Your Meds, and More. The Cheat Sheet: Do you live with an undiagnosed sleep disorder? Evolution suggests such disorders are becoming increasingly common. Anybody who has over a 17 and-a-half inch neck has about an 82% chance of having sleep apnea. And 56% of people at some point during an average week will have a bad night's sleep. Why do some people tackle the world best as early birds while others are more effective as night owls? What's your chronotype: are you a lion, a bear, a wolf, or a dolphin? Learn how living according to your own chronotype can make dramatic improvements to your life in as little as a week (even if your significant other's chronotype doesn't match yours). And so much more... A gift from the heart is always worth giving -- like farm-to-table and artisan florist bouquets from bouqs.com. Art of Charm listeners enter promo code CHARM to get 20% off!
