Stress: Can make you tired weak, depressed, or sick
Laugh With Friends: Going to a retreat with friends is a great way to get more laughter in your life. The contagious effects of laughter may mean you'll laugh more than you otherwise would have, plus you'll have jokes to reference at later times. .
There is no such thing as... too many friends, too much laughter or too much fun
Getting away from the every day stresses of life for the weekend allows you to have "me time".
