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.
Skin cells, meanwhile, are longer lived. Grafts can still be successful if taken 12 hours after death. In order for fingernails to grow, new cells need to be produced and this canât happen without glucose. Fingernails grow by an average of 0.1mm per day, a rate which slows as we age.
