Coffee makes you smarter

I have a travel coffee mug that a good friend bought me that says on it “coffee makes you smarter.”

Coffee makes you smarter

 

Occasionally I run across an article that confirms this is true. A BBC story says that “Coffee may cut the risk of dementia” and also reminds the reader that previous studies have show that coffee may lower risk of Alzheimer’s Disease. It apparently does this by limiting (or preventing?) blood-brain barrier leaking. Who wants blood-brain barrier leaking? Apparently people, who unlike me, don’t drink coffee! The article doesn’t go so far to say that coffee makes you smarter, but they wouldn’t want that to come out because they want us to think they are smarter then them. If we all drink coffee, these scientist types won’t be any smarter than the rest of us.
