Carrying human beings at 580 kmph on the ground !

Yesterday, a french train experimented travelling
at 580 kmph on the ground ! I would have applauded
it as a great scientific acheivement, if it was for a
freight train, but to carry human beings at such an
high speed ?

Human beings are not goods that can be carried around
at such high speeds. They have a complex circuitry
which is a great wonder.

Has anyone analyzed the effect of human body being
transported at such a high speed ? What about the
effect on brain, heart, nerves and other complex
parts ?

Regular flying by airplane itself takes a toll on
the body. Ground travel at such high speeds is
even more dangerous. Can someone do a bit of
research and find out if ground travel at such
speeds is safe ?

move people !

why not countries work together to move people from the
most populous countries to the ones which have lots of land ?

After all, its the people which make nations, so barren lands
can be populated with people from crowded countries...
