I know better than the medical professionals ...
1. My mum tans in tanning beds constantly to the point where she looks like the outside of a baked potato. I told her one day she should stop because she can get skin cancer, and she told me that it's not possible with tanning beds.
2. About 15 years ago, before the whole gluten-free trend, I worked with a guy who was a vegetarian. We worked side by side just the two of us and got along really well. One day, I got curious and asked what lead to his vegetarianism. He told me he had been having some health problems and went to see the doctor. Doc ran some tests, and told my friend that he should cut wheat out of his diet. This guy says, ''Well, that doesn't sound right. He must have meant meat instead of wheat.''
3. Old man I knew always had a bandaid on his nose. He had a cancerous growth on it and he would cut it off himself. He would always say: "All the doc will do is cut it off, I can do that myself and save $200."
Guess who died when the cancer spread elsewhere?
