My encounter with the tree in my back garden has reaffirmed to me the value of wearing a helmet while biking. Which, of course, I always do ... except in my back garden.
On Wednesday, while I was out, I was hit in the face by a flying insect which then gave me a very nasty sting; my face is still swollen from it. And I can't count the number of times I've gotten a flying insect in my mouth. Plus getting rain on my glasses means that my vision is very blurred. So I had a think.
And went on to Ebay, where I found a full-face helmet with visor, intended for use with motorcycles, but I'm not picky. £33 has bought me some serious head and face protection. It might be a bit over-warm in summer, but that's a problem for several months time.
