I am sitting outside at my laptop typing this in 33 degrees and the black plastic keyboard is getting so hot it hurts my hands to type! I may have to retire inside before I finish this post!

The goal is to spend some time outside every day, exposing some skin and making vitamin D naturally. The goal is not to stay inside for 50 weeks of the year and then burn for two weeks on holiday!

Breast cancer and prostate cancer are the most common cancers in women and men (respectively) in the UK.
Personally, I think it is important to remember that while skin cancers are quite common, they are also among the easier cancers to detect and treat, so survival rates are high. Skin cancer mortality in the UK is very low compared to breast, prostate and bowel cancer. In my opinion, if good high levels of vitamin D offer proven protection from breast, prostate and bowel cancer, then the small risk of Read more
