Thanks for the suggestions all, just to add some detail, I was fortunate to receive a Kidney transplant just before Christmas donated by my hugely generous brother.
As a consequence I am full of anti-rejection drugs that cause you be susceptible to melanoma, apparently statistically 1 in 5 go on to develop it, so I'm not taking any chances.
If I could think of a way to keep the 7 I would, other than only going out at night i'm stumped.
