Holland/The Netherlands is a nice country.
The amount of bicycles is directly comparable to the low number of obece people, isn't it? You simply don't see lard balls rolling along the streets, but it's normal to see couples in their 80's having an evening bike tour.
The bicycling is easy in a country where there are no hills. It's the same in Denmark. My friends in northern Greece laughed aloud when we talked about biking. With a quarter mile altitude difference every mile, even more, up and down, sure makes biking impossible.
