Vitamin D from sun exposure can be life-saving

Every year I walk in the Scottish mountains, climbing steep, rocky slopes. So when, eight months ago, I had to stop and lean against a garden wall while walking up our street, I knew something was wrong. I was out of breath - perhaps at 76 that is not so surprising, but until then I had been very fit.

It was not long since I had climbed the Aonach Eagach, the rocky northern ridge of Glencoe with two 3000-foot (915-metre) peaks, a challenge that had taken me eight hours of walking and climbing. My GP looked at my pale face and my white hands. It was not a difficult diagnosis: I was anaemic. A blood test at the local hospital showed that my haemoglobin was half what it should have been, so he sent me straight to University College Hospital, London (UCH). By the time I got there, my haemoglobin had sunk further, from 7.5 to 6 (for an adult male the normal range is 13 to 18 grams per 100 millilitres of blood).
