Continue to be impressed by plank-balanced-on-treadmill ease of laptop use. I tried writing fiction there yesterday, threading a sturdy cloth ribbon through the treadmill control panel to secure the laptop. Totally not-wobbly, and after the first minute or two of typing, got lost in composing the story and basically forgot I was on a treadmill. Walking at a slow and comfortable 1.5, looked up an hour later, startled.
I suspect I could've done that for hours -- right now, the biggest disincentive is just remembering to go down to the basement and actually start working there. For example, I am currently typing this from my bed, and having been awake and typing here for an hour at least, when I could've been doing same while on treadmill. More writing on treadmill soon.
