That was very interesting. I wonder if the longer lasting effects of caffiene comes from allowing your brain to undertake a great amount of exercise in order to improve future brain performance.

When it comes to alcohol, its effects on memory and thinking skills may depend on how they are measured and how much we’re drinking.

It’s always difficult to determine the exact causes in these cases, with so many factors at play, but the one consistent finding is healthy is good, and everything is ok in moderation.
