here's how I'd go about deciding. try doing henna tat's for a while- like re-applying them on a regular basis and see how you like them after you've had it for a year. I personally think that if you can be 110% sure that you'll NEVER gain or lose any weight, and that you'll NEVER be embarassed to show it, and you'll NEVER regret it- go for it. just make sure the place you go ensures the medical saftety standards so you don't get a serious disease or infection. As a side note, henna tatoos can be just as ornate and beautiful as a real tatoo but they don't damage the skin and they fade after several weeks and sometimes months. hope this helps :)
