Are you really that clueless?
I don't give heart disease and lung cancer to others by my lifestyle choices.
Not sure why that's relevant. The cost is the same, and taxpayers pay for heart disease and cancer research even though they're not transmissible. But, if you'd like, go look at common colds which you do pass on to others by your lifestyle choices. Colds may not usually kill, but they have a devastating economic impact.
