I think it's time to declare that yoga is a fad on its way out, destined for death in a few years.

Oh sure, yoga is a tradition dating back to the Indus-Sarasvati Civilization circa 3000 B.C.

But now that your grandmother is doing the downward dog, yoga has officially reached every corner of - and every Wal-Mart clearance bin in - America, which means it's about to suffer a slow death.

Mark my words: in a few years, yoga will be to Generation X what Jazzercise is to the Baby Boomers.

Eventually, some other form of exercise will come along and become the new fad that hipsters embrace. Perhaps it's already here: bhangra aerobics, Dance Dance Revoultion, freak-dancing, cockblocking, fight clubs, etc.
