It's a bit sad, I have to admit... but I couldn't resist! I was just too tired and between falling asleep during someone's talk or playing a bit to keep me awake until the next coffee break I chose to rediscover a tennis game...
Maybe there are more sleepy people, or maybe the topic is as appealing to other as it is for me... but when looking around some are chatting, others writing proofs and others working... But then I think: what if was I presenting? :S
