It is simple. Lego is absolutely amazing to build models with, because there are pieces in every shape and colour. Therefore I can build anything I want. In addition to that when I build a new model I always get to know something new. For example when I built the «Car Race in the Twenties» I red about the architecture in this intresting decade.
But certainly the best thing about Lego is that I am always able to relax, have fun, be creative and have some time for myself.
