In the week that one of Britain's most famous Paralympians Tanni Grey-Thompson was forced to crawl off a train, Tom Shakespeare describes his encounters with crawling.

'Don't get me wrong,' Tom says, I am not against crawling.' His holidays, he says, involve a lot of crawling: in Egypt to visit the apartment of the poet Constantine Cavafy or in Italy to see the childhood home of the communist revolutionary, Antonio Gramsci.

But in day to day life, Tom argues, 'crawling is no way for adults to go about their business.'
