I had a very good friend who had lung cancer. He had a lobe removed and never really recovered. He was 41 years old. Six weeks after his surgery I took him Christmas shopping so he could buy a gift for his wife. He couldn't walk 20 steps without having to stop and catch his breath. No way I'm buying this story.
My best friend died of lung cancer 10/18 and I am in complete agreement with you. My friend was 55.
