In the dark BC age it was thought that human psychology presented a significant barrier to human exploration of Mars. Humans were social animals who could never tolerate being locked into a small space for seven months, unable to venture out into a hostile and dangerous environment.
But, thanks to young people having meekly surrendered what had previously been considered liberties, we can now draw from a pool of tens of millions of people who spent an entire year in a tiny apartment, often entirely alone, either unable to venture outside or afraid to do so. Perhaps some of them suffered reduced mental health from being sedentary and watching a screen 24/7. But for those who sailed through… this is the ideal pool from which to draw candidates for a Mars mission, no?
