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.
Here too a decreased curve index was observed in the finger subject to greater trauma [10]. Increased forces on a nail bed also likely change the rate of nail growth. The rate of growth on the nails of an individualâs nondominant hand is slower than the rate on the dominant hand, which is subject to more trauma [6]. Similarly, it has been noted that onchycophagia, a habit commonly known as nail biting and observed even in chimpanzees, increases the rate of nail growth [1,11].
