I was tempted to post this as a hobby but I came to the conclusion that there probably won’t be many dectorists on here, but I could be wrong. This post has more to just metal detecting, so I will press on. Recently, I have been listening to Stephen Fry’s Inside Your Mind, a podcast available on Audible, and I recommend it for stroke survivors who are interested in a summary version of the brain. Episode two has some very good detail on how the brain interprets vision, which for those of us with oculomotor dysfunction, this kind of knowledge can be very helpful. There is also good stuff to do with memory.
What struck me as really interesting was about the brain’s reliance on preconceived thought. The reason I found this so fascinating is that I think it provides a key for managing fatigue, perhaps one that we already practice but knowing the theory is always an advantage. The brain relies on a preconceived notion of space and action which means it can run on half cylinders while expending energy on the unexpected. This allows it to deal with unexpected activity or cognitive challenges. This, to me, sheds some light on managing fatigue. If I imagine what I am going to do in advance, it makes the task less fatiguing, in the sense that my brain has a preconceived idea of what it intends to do and while doing it, it can operate in the background without needing to fire cylinders for the unexpected. So, this brings me back to metal detecting. Before the stroke, metal detecting was a cathartic hobby that I would spend hours doing, often returning home from the wilderness just before dark.
For the first time in over a year, I have once again picked up the detector, and gone out into several fields for a few hours at a time. I didn’t get fatigued, in fact, I felt refreshed. Why? It was cold, I had to dig, and walk for a hours. Why was I not fatigued? Well, my theory is that the activity was repetitive but also a preconceived activity. Something I have done for years. A bit like how driving can be possible for a stroke survivor, yet walking around a supermarket is not so easily done. Even though we have spent time in a supermarket, time after time, in the past. A supermarket is designed to stimulate the unexpected response in our brains. New products, price reductions, packaging with information &c. I have gone out foraging, and felt fatigued. Perhaps because I was looking for something, and my brain had to be on alert, but metal detecting is different (great arm exercise too), I am not necessarily looking for something, I am swinging the detector and ambling along. A find is random. It is not expected or even hoped for. In the sense, I don’t go out with any expectations, it simply must be what it is. Anyway, I haven’t really unpacked this idea yet.
I am still working on this notion of whether we can train the brain to rely on preconceived activity, allowing us to fly low and, thus, reserve neuronal energy, and hopefully I can delve a little deeper into it, but for now, anyone who considers metal detecting glamorous. I have included a photo of one of my recent finds below.
