Tallest building

We went up the tallest building in Shanghai, it was a bit scary looking down through a glass floor. It was a bargain though, people over 60 (and no I am not) get in for 1/2 price. As they write the dates differently, and when they are born they are one, I thought I would try it so I passed my passport over and she gave me a half price ticket. Oh dear does that mean I look a lot older than I am?????? (I guess that's what 2 weeks in China does to you).
