I was in a special school for a fair bit of my life, full of spastics and mongols. Everyone else was still doing basic shite while I was the only one getting extra education due to the fact that I was one of the rare few people there that wasn't mentally retarded. By the time I got to secondary school, my previous "extra" education proved to be inadequate, I realised I knew fuck all of the most simplest of things. Special/spazz schools here only seem to be holding pens for retards really, in the guise of "education".
I'm not too worried about my gums though, it's easily sorted and they were surprised on how healthy the actual teeth were. Only had 2 fillings in my life, the last one was due to my tooth being chipped in a fight. No signs of decay.
