I just realized we are headed towards a future predicted by the movie Demolition Man, staring Sylvester Stallone and Wesley Snipes.
"It is explained that anything "not good for you" is deemed "bad" and therefore illegal, including alcohol, caffeine, contact sports, non-educational toys, meat, spicy and unhealthy food, table salt and tobacco. Firearms can only be seen in museums. Physical contact was recognized as causing the spread of disease and is now seen as unusual. Even high-fives have been replaced with energetic waving. "Sex" is no longer a physical act for the same reasons, and even kissing is not condoned. Instead, "Vir-Sex" is performed by using sex simulators worn on the participants' heads to replace physical intercourse. Procreation is carried out in a laboratory; abortion is illegal, but so is unlicensed pregnancy. Toilet paper has been replaced by a set of seashell-like items, though their method of use is left unexplained in the movie (though Stallone later suggested a possible method in an interview as told to him by one of the film's writers[4])."
