Walking is Healthy

It's much better going to work using public transportaction than going by car - and not just for the environment.
That daily walk to the bus stop or to the subway (Americans call it the subway and te British call it the tube) helps one to stay in shape.
Now, a Canadian study tells us its exact benefits: those who choose public transports to go to work have three times the possibility to doing the minimum daily workout recommended  by experts.
The minimum recommend workout, according to The Heart and Stroke Foundation of Canada, is 30 minutes per day, 5 times a week. This is enough to improve our health and to prevent cardiovascular diseases.
"Thinking that we must go to the gym to exercise is wrong" says Professor Frank, remembering how, in the past, walking was keeping us in shape. Unfortunately, he says, we deleted walking from our life style".
According to the researchers, we should improve public transportaction to incentivize people to do that little, healthy exercise, which will indirectly improve also the public health.
That's more urgent: according to the Health World Organisation, 1.9 million of people die each year because of inactivity.
