Back in the days when I used to walk 2 – 4 miles every day, I played fiction book-tapes on a Walkman for company. …
I do the same out walking with blogs, news and drama downloaded from the BBC and other sources.
However, what I can listen to depends on hugely on what else my brain is doing, or supposed to be doing.
I can listen to drama whilst walking or driving, but not whilst working a machine, writing programs, or doing tax returns etc. But I can listen to music whilst doing those things, and it often helps me concentrate – better than working in silence. Not always though: anything needing deep thought demands quiet and above all no interruptions! I can do arithmetic whilst listening to music, but not algebra. Learning new tricks with 3D-CAD requires silence, but I once learned, I can apply them with radio on. Unless several CAD commands need to be applied in sequence – seems I can't plan whilst distracted by anything.
All this is a clue to which parts of the brain do what. Walking is almost automatic, leaving the brain free to concentrate on other stuff. Other activities bring other parts of the brain into play, and deep thinking seems to need minimum distractions. I was nearly in a motorway pile up once. In three lanes of heavy traffic, at 70mph, a loaded roof-rack came off four or five cars in front. As the debris landed in the road, all three lanes swerved and braked to avoid it and each other. Total chaos, and I remember a caravan high on one wheel weaving along the hard-shoulder. A miracle no-one collided. Truly terrifying, and the effect on my brain was striking. Everything switched to black and white in slow motion. Apparently, the brain stops processing colour in an emergency to free up brain power to analyse fast moving disasters, which feel as if time has slowed down. Extreme terror can cause loss of bodily functions for the same reason; managing sphincters is low priority compared with reacting to a fast moving death threat!
For learning audio is good for grasping principles and learning languages. Video is even better. But neither is a good way of assimilating detail. I find textbooks, ideally supported by a mentor who cheerfully answers stupid questions, to be essential as soon as I get beyond the basics. Trouble with textbooks is they're often imperfectly written, and most mentors have a short fuse! If I can I use all these methods to support each other. A few things come easily but learning is mostly hard work!
