I start most days with 1 hour of manual labor required for my side business which doesn't require mental effort. Because I am not behind schedule, maximizing productivity is not the goal so I simultaneously listen to an educational podcast.

Is there anyone that would argue that one would benefit, perhaps mentally, from not listening to a podcast when doing routine manual labor ? Maybe trying to work 2x speed first and then listening to the podcast 2x after ? Note I do not consider sweeping/cleaning mentioned in someone else example as routine labor since there is something unique about every cleaning operation.
