Neat. We should start a club :) And I don't think OCD is a cause for concern unless it interferes with your daily functions. I personally feel it is a plus point when it comes to problem solving and research. Apart from this, I also have intrusive thoughts mentioned somewhere else on this page but they have become less intense with time. Stuff like worrying about accidents when travelling, worrying about your loved ones etc. Fret not as long as it doesn't affect your functioning.
