Scientists have found that the risk of getting cancer and heart disease is reduced when we take part in physical activity—and now they've found cycling to work is one of the best activities to do this. The study linked using two wheels with a halving of the risk of cancer and heart disease.It also showed that walking had some benefits over sitting on public transport or taking the car.Cycling to work is already popular in many cities across the world.Some authorities have built cycle lanes.as well as providing secure places to lock them up.Some companies provide facilities for their employees to get changed and cleaned up when they arrive at work.It all makes good sense—according to people surveyed in this study,regular cycling cut the risk of death from any cause by 41%,the incidence of cancer by 45% and heart disease by 46%.       Cycling to work is quicker and cheaper than using public transport.While going to the gym to lose a few pounds takes effort and commitment,cycling has just become part of the work routine.Clare Hyde from Cancer Research UK says,"This study helps to highlight the potential benefits of building activity into your everyday life." Of course,any exercise is good for you but it's thought that cycling is better than walking because the activity is longer and more intense.Dr.Jason Gill,from the University of Glasgow,said,"You need to get to work every day so if you build cycling into the day,it essentially takes willpower out of consideration."You don't need to wear skin-tight lycra clothes,as long as you wear the most important accessory,a helmet. 28.The passage mainly focuses on       .
