Humans have long dreamed of colonizing Mars.

So far, the main obstacles seem to lie in the realm of technology.

But then, there’s also the human factor itself.

But they also noticed that neurotics had a much higher death rate than their counterparts.

The primary observed emergent phenomenon occurs in the decline of the Martian population, the team explained.

Still, findings like this will definitely help future missions get their ideal crew members.

Because no matter how advanced our tech gets, those operating it are human after all.
