Reply #15: I'm just saying it is an inevitable thing

One of the things that creating manufacturing and service economies has done is to isolate large groups of people from the farm animals that Euroasians have been side-by-side with for ten thousand years, it mimics the isolation that oceans provided in prehistoric times from animal diseases.

It is quite possible that a new disease can be carried from agricultural people who are immune to the disease (from repeated exposures to the disease as it has mutated) to an "outsider" who makes contact with the farm and catches the disease as it has evolved into a more potent strain. That outsider then goes back to his/her world, and spreads the disease rapidly across a concentrated group of people who are similarly without immunity to the new superbug.

Going from hunter-gatherer societies to agricultural societies had a very big influence on our species, going from an agricultural society to a factory/office worker society will have outcomes that we have only begun to experience.
