Pretty good advice for everyone, though contextually it's making this suggestion merely for people fighting cancer who have decided to go on the "POSITIVE MENTAL ATTITUDE WALK" around a lackluster "Cancer Survivor's Park." Other nuggets of wisdom(?) on plaques nearby are "Eat a well-balanced diet," "Find a qualified physician," "Treat your cancer promptly," et al.
Here's the thing. If you have cancer, it's probably a horrible idea to immediately head out and try to get advice from a crappy monument that was plopped down near a mall. Anyone with sense would get treatment information from an actual doctor. Most folks understand this, because I've never seen anybody taking the walk, cancer patient or otherwise. So why does this exist? Who are the people who would theoretically visit this place and only realize that they should maybe talk to a doctor by reading a plaque?
