is tattoos safe??????????

athogh i have some i think that tattoos are not safe for example many types of infections can be transfered from bad or all ready use needls, some advice is that when you gettin your tattoo done make shure and check to see if the guy who is doin your art work use new needls or to be even more on the safe side after getting your work done go for a blood test it may sound dumb but is better knowin if you got anything wroung whith your blood.
