Why do my nails stop growing at a certain length (around 1/2 in.)
while others' nails get much longer?
Nails continuously grow. Depending up on their strength (which is
genetic) and ware and tear they will break off earlier than others. :)
You see the same sort of thing on dogs. If a dog can go without a nail
trim if it is out walking on cement a lot and wears its nails down.
Others have to have them clipped every couple of weeks.
