I live part time in The Netherlands. Sometimes it seems like a giant old folks home with all of the old folks riding bikes all over. They ride to meet each other for coffee, to go grocery shopping, to enjoy a ride along a dike on a nice day, and to go to and from work. BTW, I don't consider anyone old folks until they're at least 70.
And, about 70% of bicycle rider fatalities in The Netherlands are people over 65 (and I think something like 50% are over 80). Many of these are heart attacks or strokes so not really a bicycle fatality but it just happens to happen while they happen to be riding. Oh, Dutch live about 3-4 years longer than we do in the U.S.
