I think you have to define what task is boring. Because walking in nature for some is complete relaxation, not boredom, But I agree when you're diong mundane things or bored in an activity, you're mind relaxes without any persuasion or influence.
So we can relax and peel back the layers and bypass what we think is important to reach pleasant nothing's.
Nice article and thought provoking ideas, laundry is more than boredom it's hell.
I have to agree on your laundry assessment, ha!
