I like to point my pointing fingers at one another in fronto of my face ( }-- --{ ) and then keeping my hands still try to rotate the fingers in cricles of opposite directions. You can do it but it is f'ing hard to pit your left vs. right brain like that. Sometimes I can do it for a while if I start them at the exact same time going in opposite directions, but soon enough my left hand will start making retarded circles.
Now you've got about a dozen idiots sitting around in front of their computers staring at their fingertips.
I would think the real brain deal here would be the single motor control area, as opposed to any specific hemisphere, the general reverse-handedness of each notwithstanding.
I disagree from the standpoint of Dick Cheney. People who have had strokes commonly experience paralysis on one side of the body opposite usually to the side of the brain which the stroke occurred. This highlights the fact of dual-hemisphere motor control.
This is the first pornsite I've found in years that I'd actually advertise to swarmers. When you first load it up, it looks just like every crappy scam site out there, except that it's real. It's huge, it's updated constantly, there's no spam, no popups, and no bullshit -- and it's completely free. When you sign up through that link above and respond to the confirmation email, I make a bit of loose change.
See what other swarmers have to say about it. People love this place, so I feel fine about sending you there and am confident you will enjoy boners.
