Decades ago, we figured out that going outside in cold weather doesn’t give people colds or flus. The cold weather forces people indoors in close quarters which is why the cold and flu spread during the cold months. The exact reason you think I’m wrong is the exact reason I’m right and you’re wrong. You should have learned this in grade school unless you’re an old boomer (because the boomers are the first gen of kids that learned what you said is a false myth).
