Friday evening we introduced our friends into ice hockey. Because the world championship in here in Stockholm there is a lot of hockey on the television. Our children want to watch all the games so we are watching the games as well. It was funny to see how our visitors liked it to watch the games. Even the next day they asked us if there is a game on the television and the Swedish team was playing again so they were happy like our children. While they were watching the game I was reading an article on the internet about osteoarthritis. A friend told me to read that information which could be useful for me.
