Every now and then, patients share their philosophy of life with me. In fact, I had that happen just today. I was running behind schedule (unfortunately not the most rare occurrence), so I apologized for keeping an elderly man waiting. It turns out he was a "hakuna matata" sort of guy, and was very pleasant about the delay. Actually, he really had a wonderful disposition throughout the exam.
As he was getting ready to leave after his appointment, he told me that he's always tried to remember "you don't have a guarantee stapled to your butt when you come into this world, and you don't get to have a U-Haul attached to your hearse when you leave."
Good point... and interesting imagery.
