A few days ago on the tube - I was sitting a couple of seats away from a middle aged man. He was sitting with his head titled forward and he was asleep. Not only was he asleep but he was snoring so loudly that I could hear it through my earphones filled with music.

In fact I am sure that the whole tube carriage could hear him snore.

In my mind a few questions pop up:

• Is he aware that by falling asleep he'll broadcast his snoring to the whole carriage?
• Does he even know that he snores?
• How will he wake up at the right stop when he's sleeping to heavily?
