An interesting section on the Beeb about "The Science of Sunshine" here:
Contains a table that outlines the pro's and cons of sun exposure.
I've been having dreams where I look around and realise suddenly that I'm sitting on a beach and the sun is beating down on me. I feel an overwhelming sense of panic and then wake up immediately, heart pounding. I'm sure this anxiety will pass, but this summer will be a big test...

Helen, great to read both your blogg and that of Lee. I was diagnosed with Melanoma 8 years ago having just lost my father to Cancer. Life is a roller coaster, thankfully I am now fit and well.
So glad to hear things are looking great for lee and also for you. My thoughts are with you. use this as something to make sure you make the most of your life, i am sure it will be a long one.
Best regards
Ian
