A shot in the dark:
Is it possible to induce a state of hibernation in humans that would substantially reduce metabolism by mimicking the chemistry of animal hibernation? What age related factors in humans would be improved by hibernation if it were possible?
It would be even better if we could hibernate with our bodies while remaining fully cognitive with a direct brain interface to the net. Have there been any studies to see if hibernating animals would have shorter life spans if they were chemically denied hibernation?
