This is an interesting question. My brain structure is a little different then most NTs. They change from a child to an adult around age 11 or 12. At that time their left and right sides of their brain finally combine together. Many NTs go on dates, get married, have children, find jobs, work for years and retire. But in my case, I was different. Because of an accident at an early age, my mind never grew up. Life was fine until age 11 or 12 and then all hell broke lose. I never made the transition from childhood to adulthood. I just remained a child. As the years passed, I just grew a mustache and everyone just assumed I was an adult. But I remained a child. Unlike adults, I never stopped learning. My knowledge became huge. Life was always interesting. There was always something new and exciting to learn. Now I am 74 years old. I suffered a massive stroke two years ago. It was a life ender experience. But my mind is still learning, and learning, and learning.
