Don Firth: "Ludicrous!
Also, I see that GooFuS is still in denial."

Denial???? denial of what?..that they have not found a gene????
So how can it be 'genetic' without there being a 'gene' involved??.....
and don't bother putting up the one with 'three markers'....the 'gene' I told you about......There is no 'gene'.....that's just your rationalization that ran out of steam AND evidence!!!

It's behavioral, nincompoop!
That's why the 'P.E.' thing is somewhat humorous in itself!

Simple as that.
