Only Hurts when I Laugh

On the street leading over to the gym I pass (from memory): renal care, dialysis, prompt care, convalescent hospital, veterans' mental health and outpatient services, children's  health, pain therapy, clinical lab, allergist, internist, cancer care.  

I think I may have missed some.  Lester Thurow the economist used to say we can't get rich taking out each others' appendix.  His attitude strikes me as a failure of imagination.
