Science is a tool, that's all. It can inform our decisions but it can't — and shouldn't — make decisions for us. There are some questions science cannot answer.

There is no “zero risk.” There is only acceptable risk and each of us should decide for ourselves how much risk we’re willing to accept for the benefit of our health, our finances, our families, and all the other trappings of our lives. To do that, we’ll need to question what we’re being told to think.
