What adult activity is better/worse than you thought it would be when you were a child?

As someone who has had an interest in cars since childhood and still mostly only plays racing video games, driving was massively disappointing. Boring, slightly stressful and quite dangerous. I don’t even have a car, because I can get by without one in my Euro city. Owning a car sucks as well with all the things that can go wrong, the fuel price and the other taxes involved.
