Many of the things we rely on for energy end up ultimately depleting our vigour, such as drinking coffee or swallowing batteries. Endeavour a new energy renewal with today's Groupon: for $15, you get a Harmony Balance-Band from Harmony Balance-Bands (a $40 value).

Harmony Balance-Bands, made of tourmaline, seek to stimulate healthy physical activity and improve daily life by emitting approximately 1,500 negative ions per cubic centimetre. Some scientists suggest that wearing the negative-ion-emitting bands helps balance the high percentage of positive ions squatting in the atmosphere, which can cause impaired heart function, weakened bones, and constricted blood vessels. Each colourful bracelet ($40) encircles the wrist in an effort to neutralize free radicals, revitalize cell metabolism, enhance immune function, and break down the fourth wall. By donning a wrist wrap 24 hours each day, customers often claim to sleep more deeply than a store-bought baby and exercise with the vigour of a bubby aerobics instructor. Because the bands are free of magnets, pregnant women and swimmers are also able to sport the Harmony Balance arm belts.
