i don't think that's called a zit anymore, but more than likely, if you live to be 80 or so, you'll have one of those eventually.
most people have a few of those growing. you don't notice it, but they are there, typically on the back.
have fun. most people get them removed by a doctor (my dad had one removed recently where there was about a 1/2 cup of puss), but this is acceptable as well. they did it right, but might should have used slightly more aseptic technique.
