One cup a day will change your brain!!! by 45% less blood flow.

What was the "one drink" she had? Just curious is it possible that there was more milk and sugar in that cup than coffee? Because if just one coffee can slow the blood flow by 40% I'm thinking that the amount I consume should stop it entirely!

I don't know whether to believe it or not! I do 2-3 mugs a day! Good thing I'm not addicted to caffeine, I can go months without coffee no problem.

Where did the blood go instead? Probably creating some fun in the pelvic area????

So I've believed my entire life that the effects of caffeine on the brain is to constrict the capillaries, and just like with a garden hose that has a nozzle restricting the flow of water, not as much water goes through the nozzle when it is set to the lowest opening vs full open, but the water has a lot of force and is used to clean stuff. I would imagine the dynamics of constricted capillaries is beneficial to keeping the brain awake, so don't be too eager to assume that this study is a negative for coffee consumption in moderation. My apologies to anyone with biophysical knowledge for the layman's explanation.
