By the numbers, this is the safest the world has ever been. The fact that you literally don't know anyone who has had smallpox attests to that.

Perception of risk is not actual risk. Yes, everyone dies, but that's more of a biological fact than a statement about how safe this world is. If you're really worried about you and your family, watch what you eat and hit the gym a bit, because statistically it's going to be a heart attack that gets you.
