This shows how short the collective public memory is. There are still people alive today who had polio. I knew an elderly gentlemen who’s face was half paralyzed from having it as a child. Vaccines have increased lifespans and improved the quality of life for humans around the world. Advancements which are now in jeopardy because people lack critical thinking skills and are highly susceptible to bullshit propaganda.
Once everyone figures out your can fix things pretty much regardless of where you are, they start to form the expectation that you’re going to do that every single time.
