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.
Another popular theory is that fingernails grow faster because they are closer to your heart, and therefore receive more blood. This idea is buttressed by studies like Beanâs (because your circulation slows as you age) and others that show fingernails and toenails grow fastest during the summer, when our circulation is best.
