Doing the most difficult tasks early in the day before eating a heavy meal. After lunch my brain shuts down and I can only do simple admin that needs little creativity.

Weirdly simple. It does not have a rotation motor. It is quite old.

In my Flat we still have a microwave that does not have a rotating plate. Insteadt it has a spinning rotor in the roof that deflects the waves in order to cook food evenly. It works well but it is needlessly complicated compared to modern microwaves.
