"Anyway, my adventures had run out by 1982 when I made the worst mistake of my life by shutting myself away to work night and day on this book. I gradually became worse than bored until, as the year came to a close, I knew something was very wrong with me. I could not sleep and the thought of food- even breakfast, my favorite meal of the day- made me ill. As a teen-age Merchant Marine sailor I had never been seasick even in North Atlantic storms. As a flight instructor, I had never known airsuckness in all my years of teaching acrobatics. Now my force-feedings left me nauseated. I no longer bounced out of bed, awakening to sunrises full of plans, expectations, and promises. A fog had rolled in and with it came fear, cold and stark. I have always worked to remain in good physical condition and all medical tests failed to find any problem. Then they sent me to the last department, Psychiatry. I had reactive depression. As a psychiatrist explained it, I had lived a full and productive life only to become a recluse in my self-made prison. I learned then that depression is a disease; for me, accustomed as I was to boundless good health, it was the worst sickness I have ever known. In these more enlightened times, help is finally available in some measure for the millions who suffer from depression. Just recognizing it as a disease that can be treated has been a major step."
