Im a heavy metal fan. I'm a huge ozzy fan. Ozzy has parkinson's. That's why he stutters when he talks, but when he sings it's clear and no stuttering. So there could be a link to it some how. I tap my foot sometimes I know that helps me. Wild shit, all I know is if we can have a satellite in space that can see a quarter in the ground, and tell you if it's on heads or tails. Why the hell can't we invent something that can get rid of something as simple as a stutter? Mind blowing
