A microlife is thirty minutes of your life expectancy. You can use it up by chilling for 30 minutes or you could start to speed through them by smoking a few cigarettes or having a few drinks. A simple way to bring difficult to grasp long-term, slow burn risks into a unit that can motivate you now and a handy way to compare risks. Even better, you gain a microlife with 2-3 cups of coffee. Win!
