Davluri, I'm sure a separate thread would help. I also think that information like this in a helmet thread can't hurt, since the helmet discussion cannot occur in a vacuum. The "Is it a worthwhile idea?" questions and inevitable accompanying "Yes it is" or "Hogwash" answers don't do any good without some empirical evidence of what a possible outcome to rapping your dome off the ground without one could be like.
Inevitably, I manage to surf onto a helmet thread while I'm having one of those days where I'm doing my best to keep my lunch down as it is, and then I read a post from some guy blasting helmets. Sometimes I shake my head and move on. Sometimes I post. I try to refrain from being an asshat as much as possible when I'd really like to say, "Hey, why stop at wearing no helmet? Go the distance- plug a toaster in and balance it on the side of the tub while taking a bath to prove how much of a renegade you are." After living like this for the last six months, both seem to be fairly equal on the list of things to avoid.
Davluri, I'm curious: what illness is affecting your thought process? I hope that I'm not overstepping bounds. I have the double whammy over here between the TBI itself and the medication to control the incessant migraines from the TBI. The TBI annihilates your short term memory to begin with. The medication further does a job on it.
When you injure or kill off brain cells, they don't come back. You can re-map areas, or detour, but that matter is gone. I asked my neurologist if I would ever be "myself" again, and the answer was kind of a bummer. You can work very hard to regain as much process as possible, but you are never the same. He said that typically, wherever you are two years from the time of your injury is going to be the new you.
I tried to get my mind around your analogy with the jukebox. I'd modify it by saying that all of the records are still there, but the pathways to access those records might not be.
