I have had more than one near death experiences. I was given too much of an anesthetic and came to just after they had shocked me back to life.
I had a heart attack and had to have my heart stopped and restarted.
I was loosing a pound a day with Graves Disease, and was so weak that I could barely walk without assistance.
I was in a boating accident in which I miraculously did not drown, but none of these things left the lasting trauma of COPD.
