It is common lore among hackers (and in the electronics industry at large) that the chances of sudden hardware failure drop off exponentially with a machine's time since first use (that is, until the relatively distant time at which enough mechanical wear in I/O devices and thermal-cycling stress in components has accumulated for the machine to start going senile). Up to half of all chip and wire failures happen within a new system's first few weeks; such failures are often referred to as "infant mortality" problems (or, occasionally, as "sudden infant death syndrome").

The U.S. also has the highest incidence of sexually transmitted infections, teen pregnancy, and infant mortality in the group.
In Alabama, infant mortality rates are the third highest in the nation.
Will infant mortality decline to the level of the Netherlands?
