Day 310 and 311 - There's not an app for that.
I think a lot when I run, even when I'm trying not to. Sometimes I get a break from the chattering in my brain, other times I solve the worlds problems, obsess about my own, recreate conversations or scenarios.......
of 'if this happened, I would say / do <insert perfect thing>..... I even think about what to blog about, or experience something cool i'd like to share, only to get back to the computer and have my brain go blank.
Or even more common, I get flooded busy doing lifey (my new made up word) things and blogging it down takes a back seat.
