Interesting study I thought I'd share. For you older men whose wives might grill you on having the blue pill (Viagra) just share this with them.
To me it makes a lot of sense that a pill that would reinvigorate the little head might also help with the big one. Although it might be a false correlation simply because sex drive is probably one of the first things that goes in dementia and Alzheimer's is one of those diseases that is decades in the making in most cases.
