I have seen a few tv programmes about families struggling in poverty where the parents have numerous tattoos. People can spend their money on what they choose, but I can’t help wondering if the cost of the tattoos has contributed to them not being able to support their children. It seems to be addictive, in many cases, ending up with the person looking like a badly-arranged picture gallery.
On the other hand, if you can afford it, and think that tattoos are attractive, then go for it. There is nothing unreasonable about deciding what to do with your own body.
