CAMERA ISSUE
Yes we did lose the video file from the GoPro filming the working out! So I had to recreate it using a scan of the pages. Which raises a question: which do you prefer? A GoPro pointing at the notes (like from 11:31 onwards) or an animated scan (like up until 11:05)? Let me know your thoughts in the comments!
