I drink a lot of coffee. By a lot I mean A LOT, and it bothers some people enough that they nag me and tell me if I drink too much coffee all kinds of bad things will happen to me. When I reply, "Like what?" they generally hem and haw because they have no research to back up their assertions. I'll readily admit that nothing is good for you if you ingest too much of it, but I don't think I've hit that point with coffee so I don't worry too much about it. If I did happen to worry about it I now know, thanks to this website, how much coffee I can drink before I'll die. BTW, it would take 445 cans of Coke Classic to put me six feet under. Useful info.
Does it mean “at one time”? Or is that a per 24 hour period limit? Also, from those tabs in your screen grab, does that imply that people in the UK or Australia have different limits? Excuse me while I go pour my 75th cup of coffee of the day.
Good question on the one time vs. 24 hour thing. The different tabs reflect the fact that those areas have different drinks. For instance NZ/Australia have something called Buzz Monkey which I think might be an all-time great name for a drink. Also makes a great question: How many Monkeys can I drink before I die?
