Good link Dotty.
I'm back to using sunbeds at the moment. I'm a natural blonde and have very very naturally pale skin (verging on milk white!) and scattered freckles. Regardless of my pale skin type, I actually tan pretty easily. I used to use sunbeds years ago but stopped after I started working in London and the nearest tanning salon only had high powered sunbeds (I was on the bed for 5 minutes a time and I found it too intense). Now I've taken them up again but I do only ever use the lower powered beds.
It purely is a vanity thing. I simply like having a tan because when I'm 'pale & interesting' my skin shows up every single flaw, plus there are lots of colours that I have to avoid wearing. When I'm tanned I can wear anything and, frankly, I feel confident naked!!!
But to put things into perspective, Dot's link summed it up for me. I'm probably more worried about my binge drinking habit at weekends than I am about getting skin cancer from sunbed use. If I am to worry about cancer, then I would be more concerned about the chemicals which are added to processed foods and their longterm affects rather than sun exposure. I think convenience food is another contributing factor in the increase of cancer over the past couple of decades.
And by the way, I've never ever smoked, but I have been a passive smoker for the past 15 years.
