Blood flow in Sauropods

Hi people,

I recently learned that Giraffes have special valves in their necks to

And, on a lighter note; Don't we love chain letters and gonzo posting to the
list from those that don't give a rat's femur!  :-) Maybe the fireballs and

the "spirit" to act without regard to the outcome. I know, they are
expressing the politics of absurdity, as per example of our current
"statesmen"(?). Don't get too upset with me folks, I am trying to deal with
the recent postings as lightheartedly as I can.
