As if you weren’t already drinking a lot of coffee, a review of several studies has found drinking three to five cups a day could reduce risk of Alzheimer’s disease by 20 percent.

Many believe that humanity's caffeine addiction has wrought a lot of good.

 The research was presented at the 2014 Alzheimer Europe Annual Congress, and found that people who drank coffee regularly — all you lifers out there — were less likely to develop the debilitating disease. Alzheimer’s, perhaps the worst type of dementia, is a progressive disease that works slowly, first making it difficult to remember newly learned things, and later on making it difficult to remember early memories and family member’s faces, while also causing hallucinations.
