When going through the Project management processes it somtimes becomes clear that one in in the right church, but the wrong pew.

Of course some of the "elderly" would prefer to ride the high end bikes of their youth; they're smart bikes meant to last and relatively cheap. They just need a 650b conversion to do all the things you want to do with a bike. There's something to be said for recycling regardless of age,
