I've read of a handful of studies linking reading and eye disease (glasses).
The cost of a lifetime of eye glasses and Dr. appointments must easily top the costs of smoking and obesity combined.

You are a genius, sir. In addition, it appears that the main cause of dental problems is consuming some type of food. If we just stop eating at all, we would entirely eliminate the need for dental insurance. I'm sure this is just the tip of our cost savings iceberg. Lettuce see what else we can come up with.
