Micromort

A micromort is a really small unit of measurement scientists use to talk about how risky an activity is. It's kind of like counting how many grains of sand are in a sandbox. But instead of sand, we're counting how much danger is involved in doing something like riding a bike or going skydiving.

For example, let's say you want to go bungee jumping. Bungee jumping is really risky because you could fall and get hurt. But, the chances of actually getting hurt are very small. It's like rolling a die and hoping you don't get a 1, which means you got hurt.

Scientists use micromorts to measure the chances of getting hurt during different activities. They say that bungee jumping has about 1 micromort of risk. That means that for every 1 million bungee jumps, there will be 1 person who gets hurt.

Now, let's compare that to driving a car. Driving a car has about 8 micromorts of risk per hour. That means that for every million hours that people drive, 8 people will get hurt.

So, when we talk about micromorts, we are talking about how much risk is involved in an activity. It's a really small unit of measurement, but it helps us understand how dangerous or safe different activities are.
