I actually learned something interesting from a book on DID. For one, different alters obviously have different ways of talking, writing, acting, etc. They often have different IQs, interests, skills, etc. They have now found out that different alters even have different results on brain scans

. Like, if a child alter is out, it reads the same as a regular child's brain! To me this is concrete, without a doubt proof!!!
Oh, and when my psych teacher brought this up, he mentioned that apparently people are trying to find a way to reciprocate DID! Obviously without the trauma, memory loss, emotional issues, etc. This is because the average person uses 10-20% of their brain capacity, whereas the average person with DID uses 85%!!!! I heard this and I was like, "booyah suckers!!" lol not quite like that but it made me realize how many advantages there are to DID, which kinda balance out the negative. If you think about it, it makes sense. To use myself as an example: between all my different alters, we: play drums, guitar, piano, bari sax, clarinet; play basketball, hockey, baseball, and tennis; paint, draw, write, and read at a very advanced level; and excel in english, math, CNA work, physiology, chemistry, academic writing, medical terminology (basically all things medical or health-related). This list is by no means exhaustive. If a "normal" person (sans DID) were to list all these talents, they'd be taken to be egotistic or a prodigy! I've always been amazed by the number of cumulative talents people with DID possess.
I thought that was interesting...
