WARNING SOMEBODY, IN ADVANCE OF A POTENTIAL ADVERSE EFFECT OR POOR OUTCOME, SHOWS THAT YOU HAVE FORESIGHT, ARE CAREFUL, HAVE WISDOM AND EXPERIENCE, AND ARE THOUGHTFUL. TRYING TO EXPLAIN, AFTER THE FACT, WHY SOMETHING TURNED OUT POORLY SEEMS MORE LIKE YOUR MAKING EXCUSES AND DEFENDING YOURSELF. Charles Tadros, M.D. July 13, 2021 Saint Louis, Missouri
