The passing of the iconic John Glenn - astronaut, senator and American hero - served as a reminder to us all of who and what's truly admirable in life. Mind-numbing apps, mediocre professional athletes who make headlines for all the wrong reasons, C-list television personalities famous for reasons no one really knows . . . these are the kinds of people who have been influencing our children (and let's face it - many adults as well). But we're in a position to change all that, to instill the values we hold dear.
