Every time I read/hear about some behavior (coffee, alcohol, breathing) having some effect (dementia, instant death, long life), I react one of two ways: 
  1. If it's negative (e.g. sporadic limb loss, uncontrollable eyeball swelling, horrific death), I say, "Oh well; everybody dies from something."
  2. If it's positive (e.g. x-ray vision, superhuman strength, non-horrific death), I say, "Sweet; another reason to continue doing X."
In conclusion, even if threatened with death, I'd still drink coffee. #psychology
