This is rather based on something strange but ancient I discovered quite a few years back that still strikes me with mystery these days; it is highly of interest for memory and training.
I had a period in my schooling years where I was attempting to write with my left hand, in general that sort of thing takes time and I was making little progress and barely visible progress.
At the time having played a lot of finger intensive video games, I was used to the burning feeling of exercise on my fingers so had a relatively high tolerance for such pain and noticed that my left hand was more vulnerable than my right to this kind of pain. As such I vented my frustration into writing random things for 2 hours straight, from combinations of letters to words as fast as I could (it looked like scribbles at some point), I felt some relatively severe pain in my hand during that time which gently subsided repeatedly throughout the time frame causing me to consciously attempt to speed up.
It looked very hopeless my writing was worse than when I started due to the pain, however at the 1:45 hour mark suddenly my handwriting changed drastically. I don’t mean a little better or a little faster but all of a sudden my handwriting was better than my right hands. At the time I believed, that something was very broken, it didn’t make sense to me that my hand would suddenly after 2 hours despite all the general right handed writing I had done all my life up till then suddenly ‘get beat’. I expected this to subside when I went to sleep, instead I woke up and wrote even smoother than the day before, it also did not look very normal, my form was strange my letters were made up of much straighter lines than on my right hand but the speed was faster than my right and the neatness better. I also noticed that my hand had some form of ‘tone’ to it before my writing improved so drastically.
Now where things get a little more interesting, a few years later I made one of my friends attempt the very same thing and they seemed to have the exact same results I have had. For them it did not entirely beat their right but was sufficiently close to it, from an almost hopeless start. Seeing this I started to run a few more tests with this friend and did other things for this time frame, simply because even though we are so different it took us the exact same time down to the minute.
We tried reading as fast as possible and similarly strange things occurred, namely we kept getting out of focus and spent time refocusing to keep the intensity high, at around 1 hour 15 minutes we got extremely tired so tired that we were passing out, then suddenly when the usual time was hit all those symptoms vanished, there was a headache and the text we were reading felt cleaner, though we didn’t really get much faster.
We tried to explain this in a lot of ways because there is no logical explanation for the time to be the same for something as plastic as a brain activity. As such we hung it on intensity. Now that I am more educated however, I do find this of strong interest because it caused exponential growth in skill of some sort, which also lasted for a long period (I can still write with my left hand sufficiently though not as neatly as back then). What is interesting is that it required working as hard as you could in that time.
I am curious if anyone has experienced something similar, or even if someone will try something similar and share any results. 2 hours for me is a lot of time these days and there are only so many 2 hours in a day so I can’t try enough things in time (not to forget that the intensity without any form of break is unbearably difficult). Given there was some kind of success with reading and with writing which are very different processes I would assume this applies generally. I would just highly doubt something like this applies only to us. It is also unlikely to be something that many others have tried I assume because it looks hopeless until that very instant change occurs and also because as I had explained with reading, we were passing out and the only thing that stopped us was the fact that we wanted to pass the 2 hour mark as a test (2 hours being the bound to securely assume it has failed).
As such I thought I would share this, feel free to leave any comments, questions or replies.
