"Feel years younger now!"  We hear claims like that frequently, especially with 10,000 Americans reaching retirement age every day. 

Can you believe any of them?  Maybe, says microbiologist Carolina Livi. 

She has been working for a biotech company and teaching at the University of Texas Health Science Center in San Antonio, exploring some of the products offered to slow the aging process.  Her work focuses on fasting and the drug rapamycin.  Dr. Livi and colleague Dave Sharp visits with her analysis.
