My Dad died at age 67 from esophageal cancer. He did not smoke. He was otherwise healthy. B4 he died he said:
“Watch out for the gluten and stop eating sugar”. Turns out, sugar causes esophageal cancer. Thanks Dad, for teaching me what you knew.
My Dad wrote a letter to the family of Dr. Martin Luther King. They wrote him back. I remember him telling me about it. I was preoccupied with something else at the time and I never had a chance to read the letter.
