i think one of the main differences is how unhealthy children are.
people in the old days ate way less, and were outside WAY MORE.

parents have little or no regards to nurtrition. more than half of what people buy in grocery stores is terrible for eating.

if children ate healthily, took their vitamins, got exercise, and knew the importance of hand washing..
things wouldnt spread as easily.
end of story.
its all about healthy immune systems, and sanitation.
i would love to hear a story about a child who follows strict eating guidelines concerning healthy foods, took supplements, got regular healthy exercise, and knew about hand washing... and i'd love to see if he/she got ill a lot.
