I recently ran across a reference to the internet site DeathClock.com.
I clicked over to it, and entered a few simple facts about myself—birthday, gender, temperament, BMI, smoker/non-smoker—and the site spat out a projected death date that was quite startling in its specificity: Saturday, February 25, 2045. (It also provided a countdown clock that showed the seconds of my life slipping away. Yipes.)
Louie Helm‘s insight:
DeathClock is crude, morbid, and effective motivation.
