 DW> What sort of UV?

dunno... i know that its a portion of the spectrum and that some is more or
less harmful that other... you experiance seems to show that you have more
knowledge and understanding about it than i... the only thing i can offer,
then, is for you to drop by that site and take a read... there's even a
section that explains some of it in scientific terms... just start at the
top with www.safesun.com and go from there...
