Cycling
What's the furthest you have ever cycled?
Perhaps you cycle to school or to work, or maybe at most a short cycling trip with friends? How would you feel about spending months on the road travelling solo from the UK to China, by bike?
For British cyclist Pete Jones, camping rough and cycling long distances through inhospitable terrain are second nature. Mr Jones is currently undertaking a mammoth trip across the Eurasian continent from Britain to China. Pete Jones is no stranger to China. But he says many people there are puzzled by his passion for cycling, asking why he would choose to cycle when he can afford a car. Indeed, while there are an estimated 400 million bicycles in China, where it has long been the preferred form of transport, rapid economic growth has fuelled an explosive expansion in car ownership.
Edward Genochio, another British cyclist who completed a 41,000km trip to China and back, said one of his aims was to "promote cycling as a safe, sustainable and environmentally benign means of getting about". In the UK, the last few years have seen a rise in the number of people choosing two wheels over four, with some estimates saying the number of people cycling to work has almost doubled in the last five years. Politicians also see cycling as a way to boost their eco-credentials, with people such as London mayor Boris Johnson often riding to work under his own steam. But we may have to wait some time before we see him emulating Pete Jones in attempting to cycle all the way to China!

Considere o excerto a seguir, retirado do site do jornal britânico The Guardian, para responder à questão.
Homeopaths believe that illness-causing substances can, in minute doses, treat people who are unwell. By diluting these substances in water or alcohol, homeopaths claim the resulting mixture retains a “memory” of the original substance that triggers a healing response in the body.
These claims have been widely disproven by multiple studies, but the National Health and Medical Research Council (NHMRC) has for the first time thoroughly reviewed 225 research papers on homeopathy to come up with its position statement, released on Wednesday: Homeopathy is not effective for treating any health condition.
