Are you one of those people who fall asleep the moment they set foot on public transport? They're special types who are generally admired and derided in equal measures.
In Hong Kong, people are now paying for the chance to fall asleep on public transport. The Sleeping Bus tour is a five-hour, 76km journey to nowhere on a regular double-decker bus, with passengers encouraged to bring their own blankets, pillows and even slippers.
Kenneth Kong is the marketing and business manager of ulu travel, the organiser of the bus tours.
The lightning bolt moment of the Sleeping Bus came to Kong one day when he saw a social media post from a friend saying he was so stressed out by his job, he couldn't sleep at night.
But when he got on the bus, he was able to sleep like a baby.
