And of course, generally just natural selection.
To be fair, antibiotics should be used in cattle, otherwise feel free to eat all those parasytes and bacteria that you have yet to introduce your intestines to. But to the morons that think using antibiotics will help with their cold, please jump off a bridge, you'd do a big favor to the future of mankind.
