Trends I have wondered about

I have always wondered about people with tons of piercings or tons of tatoos, and why they get them, and how they feel about them as they get older. Another trend I have currently wondered about is ear gauging. Not that I am being judgmental in any way. Up until a couple of years ago I had my navel pierced, and my father and brothers all have tatoos, though I do not. When I went to school, having your ears pierced several times was a big thing, but I don't know why that started. Now the trend is piercings and sometimes even tatoos on every part of your face or body. Ear gauging has been something around for a few years, but I have always wondered why people, including women had it done. At least with piercings you could take it/them out when you went to work, and with tatoos you could have placed them in areas on your body that was easy to hide with clothing if need be. With ear gauging there is no hiding it. Even if you took the gauge out, the huge hole in your ear would be evident.
