I stumbled upon an article in The Lancet, volume 138, issue 3554, of the 10th October 1891, which it seems has been overlooked by the internet so far. It celebrates the rise of the bicycle, but warns against its abuse — addiction, even. It has a message that James Cracknell might like to ponder before getting too carried away with the fabulous medicinal properties of bicycle helmets: cycling isn’t dangerous, it’s those sick addicts who like to race themselves to exhaustion who are dangerous.
