Drinking strong coffee before exercising increases fat-burning, new study finds

I believe it was in Montreal that there was a study attempted for something like a Human Sexuality postgrad study, that needed to collect a certain sample size of males who had never consumed internet pornography(or something to that effect), that had to be abandoned due to complete failure to find subjects who met the criteria.

I'd imagine it would be not quite as hard to find caffeine naive subjects for a caffeine study, but not by much.

And if you did find them, one had to wonder how representative they are of the general population.
