Betty: <file_other>
Betty: Maybe you should think over you diet :D:
Steven: It seems like you can't do anything nowadays
Steven: Everything we have contact with causes cancer :(
Steven: Here's my opinion - life causes death
Betty: Seriously you shouldn't ignore this!
Steven: Come on. If you want to avoid cancer causing things, you should move to the jungle on a different planet and wear a space suit.
Steven: On this list you sent there is UV radiation causing cancer. 
Steven: Meaning that literally the daylight can make you sick. 
Betty: It's about long-term exposure.
Steven: Yup. Generally spending time outside in summer gives you cancer.
Betty: Don't neglect scientific reasearch.
Steven: I'm not. But I just think life is too short to get paranoid over everything
Steven: I fully support fighting with smoking in public places, convincing people to quit smoking, start diverse diet and avoid unhealthy food.
Steven: But I'm honestly surprised that scientist devote so much time to analyze what and how causes cancer, and there is still no certain cure for it.
Steven: The more we study world, the more substances we analyze, and the more we analyze the more conclusions we have.
Steven: So in near future we might learn that literally everything causes cancer because that's how the world was programmed 
Betty: I'm no radical paranoic Steve I'm just saying, that if you don't have to expose yourself to additional risk, then don't do it.
Betty warned Steven about some cancer-causing part of his diet. He refuses to avoid it.
