I had to smile at your depiction of the human body. Working for 40 plus years in similar occupations, I can check off most of the chemical and radiation exposure. Six years in US Navy nuclear power, submarine service, 31 years in civilian nuclear power, 20 years road racing motorcycles, my poor body hurts at 67 years of age. Still able to get out of bed on my own muscle power. I hope you have many more years ahead of you. Shaking my head at the things we did in our youth.
