You loathe these "arbitrary points" as well ?
From the moment of conception, the unborn are human beings,
Where is the scientific agreement on that ? I don't consider a blastula a human being.
In a Russian experiment in 2010 and 2011, six men agreed to be sealed up in a mock spaceship simulating a 17-month Mars mission. Four of the six developed disorders, and the crew became less active as the experiment progressed. 'I think that's just an example of what could potentially happen during a Mars mission, but with much greater consequence,' says Dr. Beven. 'Those subtle changes in group cohesion could cause major problems.'"
That happens on earth as well, it's why you have vacations or risk a burn-out.
