I had planned to go to bed earlier, but we have a young teenager who has just moved into the ‘not tired at night’ phase and it doesn’t yet feel right to leave him to shut down the house while we ascend the wooden hill.
Due to the lockdown I am missing the hour of walking that used to be part of my daily commute to and from the office, so since March I’ve been prioritising exercise on most days. I enjoy exercise for its own sake, but it’s also motivating that there are numerous articles about how desk-based jobs are literally killing us:

A wise man that once worked with me said “you can’t cheat the body”, and he’s right. But given the choice between exercising and sleeping, what’s the right balance to strike?
