Best you hang on to that then. And hoovering.
If you didn't continually cherry pick the trivial sidenotes from a post, you'd have nothing to argue about.
I'll try one more time (heavens knows why, the previous 50 posters haven't got through either)
Hoovering isn't mental load. It's a chore.
Scenario. Jane, my friend calls and says she's in the area for the evening, and we agree it's a great idea for a glass of wine and a catch up at mine that evening. The mental load is, I need to hoover before Jane gets here, but before the children are in bed, but also need to collect DS from his friends house, which must also be done before small children are in bed, but one small child has an extra hour at an activity, which I have to wait around for, so actually I was going to get the food shop done now, but I'll need to reverse those things, and do the shop later. But I was going to combine the shop with picking up a prescription for DD, and the pharmacy won't be open later, so I will have to go in now to get that, and make a double trip later. None of this is actually doing a thing. It's the essential mental juggling required when there are many more people in the family.
Do you know how that would have gone when it was just me and eldest DS? Jane phones. We make the same plan. I do whatever needs doing, without any real thought required, in whatever order, because sole DS is 10 and when I hoover doesn't matter because he won't be in bed, nor cry and need to be settled if it wakes him. There are no other children to wait around for, or pick things up for. I have to think of absolutely nothing, other than, I need to hoover..so I hoover. I just do the physical chore.
And you still maintain that the mental planning for the former scenario is unnecessary. It's just "creating work" so I can moan. (Which I'm not.) Not that the second scenario doesn't require any juggling, because there's nothing to juggle.
