This fits with findings that caloric restriction can extend the life span in rats, since near-starvation triggers more autophagy as the cells recycle parts of the...... heel bone for better shock absorption, as well as shorter toes and a big toe that is fully drawn in toward the other toes for better pushing off during running.
