18. The world's most beautiful pain
Tourists get a foot massage in Khao San road in Bangkok, Thailand.
Traditional Thai massage is renowned the world over, and for good reason: it's painful, but you'll never sleep sounder once you get back to your room and you'll be bounding with energy the next day.
The well-known HealthLand Spa offers many types of massage from quick finger rubs to two-hour full body oil marathons that will leave your muscles wondering what just happened.
