I hate the sun, and I've never liked the idea of sunbeds. I use a lot of sunblock when I go out, and I quite like being pale - it suits my goth inclinations
I had colleagues who were obsessed with tanning, and I agree that it looks wrong when you do it too much. None of them have seen any adverse effects yet, but they're still quite young. I just hope they'll lose the fixation before they do any permanent damage.
