Honestly, I don't think I have to be 30 years old and established to enjoy the sights and sounds of a foreign country. Sure your personality and interests change throughout your life, but I would just as much want to sit down on the beach with a drink in my hand and admire the sunset as I would like to go out to party with my friends. Some people are at the point in their life irregardless of age where they know what they like and what they like isn't always the fast rush of city living.
