A tattoo on aged skin will probably look like a pattern on a creased curtain, not that I would know because wild horses wouldn't drag me down that road.
rosie re (10 and (2) according to a doctor friend of mine, a dolphin becomes a whale. I do a lot of tattoo spotting (evil fascination) and I'm yet to see one that hasn't faded with age.
I wouldn't mind the actual 'being done' of it, so long as it is no worse than pricking of holly leaves. It would have to be very simple though. So as to be quick.
I don't think I would do it now though. It would be like telling a lie. If I was a tatoo kind of person, I would have had one by now.
Although I suppose people change.............
And at our age we might not have so long to regret it. (there's cheerful! )
