When people think of pandemics, they might think of a severe disease. But it turns out, pandemics have nothing to do with severity – and everything to do with location.By definition, a pandemic is the global spread of a disease that impacts a large number of people.Think of pandemics as being at the top of a three-tier system of classifying infectious disease.Outbreaks are at the base.

Twana Wilson received an Amazon Echo Dot as a gift from her husband a few months back. He thought she would enjoy having Alexa play music and read her the weather forecast, but the Echo still sits in its original box. She won't use it.Why not? Because like so many people, Wilson suspects Amazon is watching her, even listening to her conversations through her phone and laptop. "I just can't get myself to do it yet," Wilson said. "I am not ready for it."She has her reasons. She was recently chatting with a friend who was flying to Paris. "The next day," Wilson said, "I had a targeted ad for booking flights to Paris."

"Afterward I started having a stream of Jeep ads" she said.She said it's the same story if she ever discusses a product with friends via text messages.
