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.
This isnât in my head. Fingernails grow about three-four times faster than toenails. Scientists donât know what biological mechanism is behind the different growth rates. But, they do have theories based on more than 100 years of finger and toenail observations. First, in order to understand why nails grow, you first need to understand how they grow. Nails begin in the nail matrix.
