Do you sleep well, John - a serial programmer?

A bad programmer John made an error in the code, because of which each user had to spend at least 15 minutes to look for the workaround of this problem. The number of users was 10 million people. Which means, that 150 million minutes were wasted, which equals 2.5 million hours. If a person sleeps 8 hours a day, then he has just 16 hours of conscious activities. So, John destroyed 156250 man-days, which is about 427.8 man-years. The average persons lives 64 years, which means that John killed about 6.68 people.
