So the shrew that drinks beer. Certainly, it is worth some study, but surely it isn’t unusual? If I read the numbers correctly, they “drink the equivalent to nine small glasses of wine, or four and half pints of beer” over 12 hours. And this is 3.8%, not 5% (so a lot of our beer is 30% stronger). Even five pints of wifebeater is easy drinking each 12 hours. Not good for the waist or coordination, but that isn’t the issue.
I might be reading it wrong if “the equivalent” means they are actually drinking the pints of volume. As I read it, this means they are drinking the equivalent for their size / mass / volume.
