Insomnia

The last time in Bangkok, my guesthouse room was noisy 24 hours a day due to traffic from Rama IV just a few metres away and an all-night noodle stall downstairs. This time, my guesthouse room was noisy throughout the night due to the nightlife off Sukhumvit, but rather quiet in the morning when everyone was having their hangovers. I'm not complaining because both times I could sleep anyway.
But it did bring to mind someone's comment that Singapore still had some way to go before becoming a sleepless city. So maybe Bangkok is doing much better in this area. But I still don't get why it's so great to be a sleepless city. Since when was insomnia a good thing? Sleep is necessary rest, and it's just foolish to try and push oneself to keep going with as little sleep as possible. Now if some of a city's denizens wish to sleep in the day and carry on with their lives at night, that's perfectly fine. But if the number is small, it is only natural that the services available in the city at night are correspondingly sparser. No need to deliberately try and push for more nocturnal services to encourage more people to become nocturnal. Right?
