they go on about Nasa or Elon Musks attemp to populate Mars , but i don't think so ,

look how the astronauts are coming back from only a 3 month mission in our orbiting space station , they can barely even walk they need assistance and hospitalization for weeks just to get back to normal , and it takes several to eight months just to get to Mars , what kinda shape with they be in just getting there ? , never mind making it back again , the plans are ambitious but one must be realistic too
