The mid to late 2000s saw an exponential gain in popularity for zombie walks, due largely to the success of zombie films at the time, such as the Resident Evil movies, 28 Days Later, Zack Snyder's Dawn of the Dead, Shaun of the Dead, George A. Romero's Land of the Dead, and Zombieland.
A: If a toenail has completely fallen off, it can take up to 18 months for it to grow back. A toenail can take longer to grow back if the nail bed has permanent damage. In some cases, old nails do not completely fall off, and they act as a protective barrier to the nail bed until the new nail begins to grow.
As long as there is no permanent damage to the nail matrix or nail bed, the nail ought to entirely regrow and appear completely normal. Fingernails grow at rate of .13 inches per month. Toenails grow more slowly, usually close to half the rate of fingernails. Fingernails can regrow entirely in three to six months.
