It may be a long time before humans can extend their lifespans to hundreds of years, but the technology to make humans look sixty years younger than their actual age is right around the corner. A group of scientists at the University of Michigan have done an exhaustive study of what gives people the appearance of age — wrinkled, saggy, or broken skin — and figured out a quick fix that may keep skin looking taut and young even though the person inside it has grown very old. The key lies with collagen, a spongy layer of tissue beneath the skin that is gradually dissolved as people grow older.
