Ive gotten 2 tattoos in my life, and im 20 years old. I plan to get more down the road. Just make sure that they are important to you. I was told by a lot of people that I should wait 6 months before I get it, and if I still want the tat then I should go for it.I'd recommend the same to you. Make sure your tatoo has meaning, isnt highly visible (forearm,hand,calf,neck), unless you plan to do the same thing for a long time. Obviously it makes getting a job harder. Dont listen to what anyone says, its what you think about it that matters. I asked the same questions when I wanted to get my first one, and all I got was dripping sarcasm. If you find your happy as an EMT, go for it. I dont think it matters whether its a career or not, i'd be willing to bet most EMTs/ex emt's would say that it was an important/memorable part of their life.
