I have a glass of wine every night with my evening meal at around six. Then a pint of beer at eight. Possibly a bourbon before bed. I go out rarely these days, maybe once a fortnight, but when I do it's never more than four pints of beer. I'm at the limit of what the UK government recommends, but there seems to be very little evidence that what some people call "heavy drinking" actually shortens life. And it certainly makes life more bearable!
I'm drinking more (and working less) at the moment because we're having an unusually warm and sunny summer here in England and warm weather + cold lager + garden = heaven.
