People with healthy immune systems don't die of flu.
What about people without healthy immune systems? Is your immune system healthy, or is the way to check just to see if you die of the flu? Or maybe you get a type that kills you because you have a healthy immune system, like the 1918 pandemic, who knows.

Uber runs a risk in being so bold in trying to get rid of its workers. Until it has these cars in hand, it needs its driver fleet. Rational self-interest tells those drivers to maximize their income, but also to mitigate as much risk as possible.

No, this is a great Republican strategy, we will just name all beneficial things after Democrats! First there will be Obamacare, and Goresat, and then maybe something like Hillaryrail - a high speed rail network, or Elizabethbucks - A system of guaranteed federal income.

You'll see, it will pay off in the end.
