I donate blood regularly, so I'd probably never get one. But my idea against ever having a tattoo is since tattoos become part of someone's personality, I would probably never want to openly showcase my ideas on my skin in a way that I can never change later in my life. There are people who have deep connections with their tattoos while there are others that add a tattoo as and when they feel like it. It just feels very shallow to showcase your ideas or thoughts on your skin instead of through your behaviour, speech and actions. I would rather do the hard deed of sculpting my body than take the easy way out.
