Marines must request paternity leave within 25 days after the birth of the baby. If deployed, the commander can approve paternity leave within 90 days of deployment and can authorize it outside that time period for extraordinary circumstances.
An injury to a nail may result in the loss of the nail. As long as the nail bed itself wasn't damaged, a lost nail should eventually grow back. Healthy fingernails grow at a rate of about 0.10mm per day, but toenails are slower, growing at only about one half to one third of a fingernail's rate.
Because we are accustomed to nails and hair growing, not hands, feet, and heads shrinking, we perceive this change as an increase in one rather than a decline in the other. To quote the respected forensic anthropologist William R. Maples: It is a myth that fingernails and hair continue to grow after death. What really happens is that the skin may retract around them, making the hair and nails prickle up and jut out more prominently.
