I am hurt to hear of my friend Mark's death. I only had 2 or 3 really good friends in college and Mark was one. I went my way and left college behind me, and had not spoken to Mark in over 30 years. That does not matter in the least; a once in a lifetime friend remains just that, for a lifetime. God bless his family, his siblings and father Dr. John, whom I also remember very well. Dr. Mark Zakula MD, San Antonio, Texas.
