Ryan Howell, an assistant professor of psychology at San Francisco State University, found that buying experiences – such as vacations, going to the theater or renting a sailboat – gave people more happiness than buying material things.

Those at the front on the top deck are generally forward thinkers and those at the back are rebellious types who do not like their personal space being invaded, he found.
Sitting in the middle are independent thinkers – usually younger to middle-aged passengers more likely to read a newspaper or listen to a personal music player.
On the bottom deck at the front tend to be gregarious meeters-and-greeters while those in the middle are “strong communicators”. Travellers who automatically head for the rear downstairs are said to be risk-takers who like to sit on elevated seats because it makes them feel important.
