Well, it doesn't really matter. Older people still tend to look a bit different at people with tattoos. I have noticed it myself because I have two, pretty visible, but younger generation or educated people are more interested in what can you do rather than your tattoos.
Most people don't care if you have a tattoo. It only gives people a reason to judge you but this can be ignored altogether. Most hospitals have a policy that the tattoos should not be visible. It is advisable to get attires that cover the tattoos.
