Cubing does help the brain for sure. I have a interesting brain disorder called Agenesis of the Corpus Callosum (ACC), basically I'm missing a piece of my brain; the center piece that connect both the left and right hemisphere. However there are 2 types of it, partial is missing parts of it (P-ACC), complete is missing all of it (C-ACC). I have (C-ACC). The doctors would think that those with C-ACC would have more issues, its reversed, P-ACC has more issues. The 1989 movie "Rain Man" is all about my disorder, however they say it's Autism. They say this because of lack of knowledge to the public's current knowledge of it back then. The movie also played Hollywood in it. The movie is inspired by someone I've met and he is incapable of doing math. The movie had him do math and he really can't. For me however I can solve a Rubik's Cube in an average of 35 seconds and I have a passion for math. I feel that I can improve my speed but I also feel that my disorder is setting me slightly back (no big deal as I'm happy). There is a big spectrum of what people can and can't do whom have my disorder. Also this disorder effects me in many ways such as: delayed reaction time, low muscle tone, learning disabilities, social delay, and more. With cubing, I've improved in many ways with the help of cubing. 6 years ago before cubing I was struggling in school, I could not study well, I did not care as much. I also had a 2.82 GPA with getting a modified diploma and I needed to pass required tests to graduate with a standard diploma. I managed it after I picked up the cubing hobby and successfully graduated with a 3.20 GPA and a standard diploma. I am going to be featured in a Rubk's Cube documentary called "Behind the Cube," my segement is all about the brain and my disorder. If you were at USA Nationals 2014 and saw a film crew, that was them. I was interviewed then and they are wanting to film more of me. There is still a small chance, about 10% that thay may cut me out of the film, yeat they like my life's story.
