Cenegenics Medical Institute is a Las Vegas-based medical clinic that focuses on the management and reduction of the appearance of aging. Patients use a combination of diet, exercise and hormonal supplements, including Human Growth Hormone, to reduce and reverse the visible signs of aging. The company uses a photo of its Chief Medical Officer, Jeffry Life, in many of its advertisements.

The photo, taken when Life was 67 years old, shows him shirtless in a pair of blue jeans. Although his face looks like the face of someone who is 67, his body looks like that of a 30-something bodybuilder, complete with well-defined pectoral muscles and six-pack abs. He turned 70 years old on December 25, 2008.Yahoo News: Youthfulness an American obsession (December 7, 2008)
