>>13162145I cannot be bothered to dig out any articles, but it's worth thinking about the difference between coffee and caffeine, OP.
In the same way that people always conflate nicotine and smoking, they do the same with coffee and caffeine. There is evidence out there that suggests that any long-term positive benefits of coffee are related to coffee as a whole, not specifically caffeine. Further, decaff may be better for you than regular.
