But you can totally measure them with an easy trick. Spread your palm and make sure there's space between your fingers.

2Murder Mystery

The average person walks past at least 16 murderers in their lifetime. A math-loving Redditor did the equation and it's mind-boggling. You meet/ pass at least 10 new people every day. Multiply that with 365 (for days in a year) and multiply that with 71 which is the average lifespan of man. You'll get the number 260,000, which is the number of people you pass in your life. Now multiply 260,000 with 6 and divide it by 100,000 (considering 6 murderers per 100,000 individuals) and you get 15.6, which rounds up to 16.
