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.
If you are having an accident which causes the big toe nail to come off instantly, you might want to be cautious about some things to prevent more severe infection. A separated nail from the nail bed will not reattach. Instead, a new nail will grow back within a quite long time. A big toe nail, for instance, requires up to 12 months to regrow completely. This new nail might also be in a different shape from the separated one, as this nail grows after the nail bed is injured.
