I too have several things that I do to take a mental break. I do my indoor "gardening" (I have a nice collection of plants which need attention now and then), root around in DD, check out one or two of my favourite websites.
If it is lunchtime, then I go for my regular route march in the area where I work (I take my music player with me and listen to whatever is my favourite thing as I stomp along. I have been known to sing as well, so if anyone hears strains of "Ring of Fire" in SE1 then it's probably me
).
I also have a "happy file" which I add to from time to time. It contains all sorts of jokes I have collected from newspapers and our humour forum here in DD, and thank-you letters and cards that I receive from the members of my employing organisation. If something goes really pear-shaped, then I look in my happy file.
