Liposuction was the most popular cosmetic surgical procedure in 2005. There were 324,000 surgeries done in the U.S. alone according to the American Society of Plastic Surgeons.

A doctor at The University of Colorado has just received a $1.6 million grant to research where the fat returns after liposuction and if results are different for different types of people.

If you live close to Denver, they are seeking people to participate in the study. You'll get a free liposuction if you participate.
