A death clock is, as the name suggests, an estimate of the time left until one dies. Numerous "death clock" websites can be found online which require one to fill out a bunch of lifestyle information, such as an average amount of cigarettes, alcohol and other intoxicants taken in a specific time period, as well as family health history, the age of one's parents death, and other such things. Perhaps the most popular death clock website - the creatively and memorably named "deathclock.com" - claims to be "The Internet's friendly reminder that life is slipping away..."
