The age at death during the first day of life (day zero) should be recorded in units of completed minutes or hours of life. For the second (day 1), third (day 2), and through 27 completed days of life, age at death should be recorded in days. (ICD-10, 2: 131) |

Given the bump in mortality that occurs around birth, this is not surprising. |

When we get into adult life, things start to slow down. Adults are defined in ICD9-CM (xiii) as people between 15 and 124 years old. If you make it to 125, you are "hors de catégorie!" |

In this middle period, there are some indications of what constitutes a good life. It should be well ordered and rhythmic. Things should happen at the right time. Thus sexual development has its own timing: |

Similarly, problems with temporal regulation of menstruation are well definedtoo early, too late, too frequent, not frequent enoughnatural rhythms should not be upset. |

A relatively recent temporal problem in addition is jet lag: |

Irregular sleep-wake rhythm, nonorganic origin
Jet-lag syndrome
Rapid time-zone change
Shifting sleep-work schedule
(ICD-9CM, 71) |

The reference to the "nonorganic origin" highlights that this is a situation-bound condition: the context (jet travel or night-shift work) is directly folded into the disease. |

To an outside observer, there is remarkably little reference to the process of aging. An adult is a timeless being who should be healthy: |
