It could just be the cyclical nature of fads like tanning.  it could be the health consequences.  However the tanning industry is blaming the 10% tax placed on them by ObamaCare for loss of more than half the tanning salons, and 81,000 jobs in the country in the past few years.  (The cynic in me wonders how many of those 81,000 are now covered by ObamaCare?)
