A call from a friend

I received message yesterday. My friend had been feeling down-in-the-dumps so I suggested he go for a walk. I thought it might help. He called during his walk and thanked me. He said he had not felt so good in a long time.
The C.D.C. released a report last summer. It said that walking is good for everyone. The new Pope walked to a nearby church, after his Papal Coronation, addressed a congregation of followers. The first of three points in his first homeily was to walk... I forgot the other two "legs" of the message...
If you have reservations about listening to me, my friends, or the Center for Disease Control, then maybe the Pope can be a source of inspiration.
