It's another aspect of culture that makes me realise I am getting old, and things are coming along that are not for me, or people of my age.
When I was growing up, tattoos were on men (never women!) who had been in the forces, and got them done abroad, usually on a drunken night out.
They were usually dedicated to mum and dad, or sometimes a coat of arms, and a swallow on the hand was also common.
Certainly none of the designs we see now - but already, trends are changing.
People who had the solid black certificate designs are probably regretting them now, they are out of fashion, but unlike clothes, the wearers are stuck with them.
