Very nice and touching tribute. The gun will become a hand-me-down. The story will undoubtedly be told many times.
My mom was given 2 to 5 years after her 2nd cancer diagnosis. She lived 23 more years (and died of heart disease, not cancer). Some people can do it, and some can't. It took a complete lifestyle change. Only healthy food, lots of walks - every day, whether or not she wanted to. Exercise, fresh air and determination. It helped build up her strength so her body could fight.
There are non-traditional cancer treatments. Doctors aren't willing to explore. I know this man's wife. She used to be part of the family. This IS a true story and not an urban legend.
As a former cancer nurse for 6 years, I can tell you that "HIS" cancer was incurable under current methodology. The government would rather thousands of people die than to make legal things that are currently illegal for nearly purely political reasons.
Just throwing this out.
My best to his family and to his wife.
My best to you for being there for him.
