Last monday, did my usual trundle home from work and all was right with the world. Come the evening, I was all wobbly and remain so. Benign positional vertigo, apparently. What it amounts to is one of the little doodads buried in your head that tell you which way up you are gets stuck, giving the impression that you're in constant motion. The upshot is ongoing wooziness, pronounced klutzery, inability to stop turning corners and so on. Not condusive to bike-riding obviously, so I've been catching trains to and from work and speaking as a public-transport user, I find that all cyclists are smug bastards and I hate you all.
Until a week or two has passed, my somewhat psychedaelic state has improved, and I'm back in the saddle again of course. Can't believe I'm missing this weather.
