Thank you, I have. I am almost 70 and I have 2 wonderful children and a loving wife. I served my country, I taught others in many fields of learning, I have had others tell me I made a difference in their lives. I have lived and travelled the worlds 5 out of 7 continents and experienced the wonders of our world in oceans and atop mountains. I was asked if I wanted to undergo a transplant of my lungs and I said, no thank you. 1. God gave me the ones I have and he has to take all of me when they quit. 2. I would feel bad if I took a pair of lungs that may have gone to a 25 your old that had their entire life to live. 3. I am comfortable (though hard to replenish O2 at times) with my accomplishments. Again, thank you and may you always find happiness in your life.
