If you have ever wondered why Christmas bells have a special cheery sound, it is because they are made of platinum. Platinum bells vibrate at a certain frequency that has a positive effect on the brain waves. The person hearing the bells will feel that their energy level is higher, and more positive.
If you have the inclination to get Christmas bells, make certain that they are made of platinum. Ring them all year long, whenever you feel less than perfectly joyful. Ring them whenever you think of the Messiah. Ring them whenever your children are moody. Ring them whenever your spouse seems to be argumentative. Keep the cheer all year long. Keep the cheer.
