Whoops.. thank you for pointing that out. I have in fact read Blink, so that is probably where I picked up this dubious factoid. I need to read it again to refresh my memory so I don't find myself unknowingly quoting it.
It's one of those things I tracked down after seeing one to many people say it as if it was a settled fact (never mind of course that there isn't really reason to assume people wouldn't prefer an entire can of the sweeter cola)
