Buying a tea infuser is one of the best things I've ever done - real leaf tea by the cup! Moroccan mint is my favourite at the moment, but I like to experiment, and can't help but think that in tea I've just found one more thing to be geeky about.

I also find that the regular ritual of making tea helps to stop my thought processes from falling down rabbit holes, so to speak. It's sometimes good to step back and wait for kettles to boil and leaves to steep.
