Common features between games and life

Our life is similar to games: it is ruled by the same laws. A few months ago I found one article "Laws of life and play" and this topic became interesting for me. I have collected a set of articles and blog posts that deal with the same topic.
I got many curious facts and much helpful information. Hope you will also find them useful.
