I love a good IPA! I have to be careful sometimes because some of them here in America can really pack a wallop (approaching 10% abv). They'll make you forget about a lot of things. : ) We have a kind of war on alcohol going on here in the US. Younger generations are drinking less and it seems like every day there's a story in the news about how unhealthy it is. I don't buy it. I know drinking excessively isn't great for a person's health but I think when done in moderation the relaxation effect one or two drinks has has to offer some kind of benefit. Best of luck on your PHD! Cheers!
