Another unexpected finding was the connection between well-being and the percentage of residents commuting by bicycle. People living in places where they could commute to work by bike reported feelings of satisfaction and fulfillment.This could be because places with bike-friendly infrastructure might also support other types of policies that improve living in that area. Or it could be that commuting by bike improves physical health, which in turn improves a sense of well-being; a study in Heart this week showed walking or cycling to work cut the risk of dying from heart disease or stroke by 30 percent.
