Today’s children are being brought up in a dangerously clean and antiseptic environment with prolific use of antibiotics via the medical profession, and antibacterial products used everywhere. These products are counterproductive to the young body and it’s immune system. These kids will grow up with a two fold problem, with hyper-sensitivity to certain substances (like peanut allergies, being seen like never before), and a weakened or under-developed immune system that may prove lethal later in life. If we end up with a society of this type, we could expect a plague like the black death to run rampant and wipe out a large chunk of the population.
