I used to scoff at 'old' people who asserted confidently that pains in their arthritic joints presaged changes in weather.
Some years ago I crushed the bones in one big toe. I woke in the last night with a pain in that toe and today it snowed after a mild spell. This is not the first time my toe has predicted a change in weather. The lesson? Pay attention to what old people tell you. Some of it is useful.
