I find when doing software dev, I need to take frequent breaks to let my mind rest

I've found this too, but I don't usually track the breaks as work (unless at least somewhat related to one of the things I'm working on, or that we have in the backlog, like reading an article about a type of query we are going to need to use, etc.)

Are you tracking these breaks as part of your 80 hours in the 2 week period?
