Old people on bikes

There is a new (or old) phonomanon going on on the streets.
Let's say you're looking around a street, What do you see? Well there's a couple cars, a telephone pole, Buildings off to the side, some trees and a few people on bikes, wait... Look back a the people on the bikes, are they old? The chances are pretty high that they are.
more and more old people are riding bikes on the roads, Now I would have no problem with this other than the safety hazard for me and the old person going a steady and swervy two miles an hour in front of me. However it does provide entertainment, look at these pictures and try not to laugh.
