One micromort is equivalent to a one-in-a-million probability of death. Micromort statistics are typically taken from the average number of deaths in a population or resulting from an activity, though we are all exposed to our own amount of micromorts every day-an older, infirm person will be exposed to more micromorts than a younger person, for example. Your micromort exposure increases as you engage in risky activities.
