White sand beaches, sparkling blue water, and beautiful palm trees...your perfect tropical vacation is here. It’s warm, but there is a breeze coming off the ocean, which keeps everything fresh. You bring some easy reading out to the beach and find a hammock set up in the shade. Brush the sand from your feet and make yourself comfortable in the hammock.

You begin to sway back and forth…so gently. The sound of palm fronds rustling is a delight for your ears. As you watch the palms move in the breeze, your eyelids become heavy and start to close. The book lays unread on your chest. Your hammock continues to rock...back and forth...lulling you into a deep state of relaxation. Your thoughts begin to drift.
