It does make sense ... but only if it also makes sense to penalize:
People who engage in risky sex practices
Thrillseekers and extreme sports enthusiasts
People who travel to foreign countries rife with diseases eradicated in the West
Motorcycle drivers and cyclists who don’t wear helmets
But you know it will only be smokers and overweigh people.
The nannies will probably look for more. Their hunger for power never gets sated.
