What are micromorts & microlives, & how are they linked to risk?

Подробнее о видео

How do you know how likely something is to kill you? Or how do you work out how beneficial something is? Welcome to micromorts and microlives!

Just how dangerous is crossing the road? And what's the real payback on eating healthily and exercising regularly? Neither are easy to get our heads around -- especially when it comes to that ultimate measure of "badness" -- dying. To make things a little easier, "micromorts" and "microlives" can help estimate the risks and benefits of what you do -- and what you don't do.
