Right! I don't actually have an answer here, so don't get your hopes up, but your thoughts please! I buy two bottles of cold beer at the bar, they're both taken out of the fridge and opened at the same time. I'm holding one in each hand. I can only down a few before my stomach gets full and the following dilemma sets in: Asssuming I drink steadily, and assuming I prefer cold beer to warm beer, is it better to drink all of one bottle before starting the other, or to take alternate sips from each? Ponder...! (and if you feel like it, think of fizziness too, to make it interesting).
