Without that answer I could not proceed with my job. So far, my best guess about human bodies is that they work great without old age or disease when they do function optimally. Lasting at least 6,000 years and maybe as long as we choose. Able to receive all required fuel or nutrition from sunshine and the air we breathe. When humans decided to abide in fear, which curtailed their ultra high vibrational Spirit, their bodies and psyche fell in line to be much lower vibrating and thus required and desired lower vibrating nutrition to survive and get pleasure.
Animals are within their nature eating earth food.
Our bodies are obviously not designed like any other animal and only eats food because our higher vibrational digestive system and instincts are out of order. They have resorted to their normally dormant, emergency survival food digestive system. As one begins to reverse the fear motivated disease with Love from God, the body and psyche naturally start to more and more want the lighter vibrating mediums of earth nutrition and less of it, and maybe also begins to assimilate more from sunshine and the air. Once all fear has been healed and that is sustained for a period, the diet would naturally change to the intended high vibrating diet of sunlight and air. I have no idea what the fate is of the body that I reside in at this time.
