George W Bush did abuse alcohol for most of his adult life. That can impact you cognitively. Not saying he "drank himself stupid" or anything like that, but It wouldn't surprise me if his drinking accelerated his cognitive decline as he aged.

It's awesome that you have such insight into his private life, it would be even more awesome if you could source this type of defamation.
