Cycling to work 'halves risk of heart disease and cancer' | Daily Mail Online

The researchers, whose findings are published in the BMJ, studied the commuting habits of 263,450 middle aged men and women. They assessed their health for five years and recorded whether they developed cancer, heart disease or died of any cause. Adults who walked to work – typically six miles a week – were 27 per cent less likely to develop heart disease than those who drove or took public transport.
