Long, long ago, in another life, I used to work in the most wonderful shop, called "The Wine Cellar". They sold over 1000 labels of wine, and then some beers, mixers and spirits. We often had tea sitting outside, and I would make a point of sitting in the sun, (unless it was midsummer) so that I could get my 10 minutes worth of sunlight to manufacture vitamin D, to process calcium so that I would not get the old ladies common ailment, oestioporosis.
Wow, now I spend so much of my time outdoors, I can't even imagine needing 'sun time'. If we are not fishing, we are mushrooming, or I am walking to town, or just cutting the lawn with the brushcutter. I thought that, having been warned that the island gets its rain in winter, we might be short of sun, but so far we have had only a handful of days when it has not shone at all. Mostly the weather changes by the half hour, and some of the rain showers last only 5 minutes and then the sun is out again.
While that does make hanging washing outside a whole new ballgame, so far I have been up to the challenge, and we do get clean clothes to wear.
