Life on earth evolved in an environment of gravity; ubiquitous, always there. Take it away, and cellular biochemistry can run awry. Microgravity exposure in higher animals, studied in astronauts who have spent prolonged periods of time in orbit, is a harmful exercise. The longer the exposure, the worse the harms. Many of the changes that microgravity exposure causes to cell and tissue function can be viewed as analogous to those produced by aging. That said, it is important to recognize that microgravity exposure is not aging, just as progeroid conditions resulting from DNA repair deficiency are not aging, the unpleasant dysfunction of type 2 diabetes is not aging, and obesity is not aging. These line items involve the accumulation o…
