I used to feel good that many people missed some of the more common serious diseases. Now I am not sure if the price of doing so was justified.:

In the interests of good health I should go have some pickled eggs and beer daily I suppose. Only problem is the wife will inform me that also might prove fatal. I somehow think informing her that it is also good for her health is not going to work out at all. It would be pretty bad if even the dog left as well.

Anyways it is not totally proven it reduces disease. Still I see it as proven to potentially lower your costs of living though.
