@ossobuco,
To recreate the post in shorter form -
I've worked in science, land arch, and am a visual artist; have worked on housing tract irrigation design well into the middle of the night, and my first attraction to art was that I would lose myself in time while painting or drawing.
On the other hand -
When I clean house, I multi-clean, going from room to room to move stuff around, a kind of house play. I think that's a mix of boredom and play. Don't fence me in . . . to one room. I'll also make coffee when cleaning the kitchen and stop and have some while checking the computer - and then back to the kitchen again.
Actually doing two things at a time, other than walk and talk or listen to music while cooking, no.
