As long as those of us who feel the joy of pushing our own bodies through this world express that joy, as Krista does in quotes such as the following, we'll be doing our part in inviting others to join us:

These are the things make me some days unable to stop smiling inside: When I pass a string of 30 young children all on bikes, orderly in a precarious but persistent way, all dutifully wearing helmets (and bookended at both ends and in the middle with a handful of brave adults), giving me shy hellos and smiles of recognition as a fellow bicyclist. When someone standing in front of their house, watering the lawn, or getting into their car, looks up and says "Good morning!"--and really means it.
