analogue poo
When you go for a poo but forget to take your phone with you. Devoid of the stimuli of checking emails and social media you're obliged to spend a few minutes on analogue pursuits, such as thinking, meditating, singing, or perhaps reading a book or newspaper.
I'd already started to let one out when I realised my phone was on my desk, so I had to do an analogue poo. But that's ok, I came up with a great plan for the next book I'm never going to write.
