Thanks for inviting me into the future .I have always believed that our sun is the energy source that regulates life on our planet and maybe on other solar planets. I believe the DNA of all living things has been encoded at the cellular level to perceive this energy( as lethal) after a certain point and to act accordingly.That point occurs soon after we pass our moment of optimum vitality mid 30’s. This triggers aging as a natural way for the body to say mission accomplished time to go. A conscious effort to reduce one’s exposure might increase life expectency. By this i mean a radical shift from living by daytime schedule to living on a nightime schedule ( active at night and asleep and carefully sheltered during the day )with only occasional outings in the sun for seniors 70 and over could be beneficial.
