For some reason, I can focus better, yielding results faster and more efficiently.
Maybe you actually focus too strongly (on too many outside thing) and beer helps you limit your focus to only your task at hand.
I was about to ask the dependence of the results with the amount of alcohol (quantitatively) absorbed. Is there a kind of (probably person-dependent) threshold where one gets the best?
They cited previous research with higher BAC where diminishing returns occur (due to the negative impact of alcohol on cognitive functioning). A little bit of alcohol is seemingly beneficial here, but too much and you lose that benefit.
I was thinking about that (there were a couple of steemit posts on multitasking recently).
But no numbers (with error bars) I guess?
