Titusfied: yes I can detect sarcasm, but sometime i play along and deliver a kick of realism. and that's good that you aren't addicted to it and can hold your own. also don't cuss at me, i never cussed at you.

Jamesadin: i'm 99% sure. i'll have to talk to my grandma to be 100% sure that it is a genetic thing or not. i do know however that my grandpa had a pretty bad lifestyle when it came to burning brain cells, although he could play like, 12 chess games at once. or at least that's what i remember my dad telling me. anyway the cause if it, so far as i know are a combination of different things, which can include defective genes.(i just did a search on the web).
