If you needed any more of an excuse to lie around in the sun (oh, wait - that's me), there's a new study linking a lack of Vitamin D to the development of schizophrenia. Seeing as a lack of that vitamin has also been linked to higher risk of multiple sclerosis and a few cancers, maybe it's time for us to quit slathering on the sunscreen QUITE so thickly and start letting a little of that Vitamin-D-maker-in-the-sky shine on our skin. Just a little.
