How do you use multitasking?
I treat meals as ETD massage. Chewing, swallowing, head rubbing. All to relieve sinus pressure. Also helps with doing it consistently 3 times per day
You rub your head while you eat?
As a single brain person I avoid that. Every multitasking in my life is done entirely by my many multi core machines.
I try to avoid it, to be honest. I'm usually better at one thing at a time.
Same for intellectual tasks. But isn't it better to listen to podcast while exercising? Or cook while listening to music and dancing? And making poem while brushing teeth in a cold shower ;D
