The imaging technology, which has been developed over the last 15 years, used mathematical models to predict how the shape, color and texture of the face change in those who don't exercise regularly, researcher Ross Whitehead said. [Images: Photos of the technologically aged study participants ]
The researchers defined regular exercise as 30 minutes of moderate activity, five times a week.

"Weight gain is the main impact of no exercise, rather intuitively, but we also took into account various factors that affect skin quality," Whitehead told MyHealthNewsDaily. "This technique can be applied to any factor that affects facial appearance, (and) we looked at the impact of exercise."
The aim of the study was to show how an active lifestyle can improve appearance as well as health, Whitehead said. The process took into account the average annual weight gain that occurs with aging about 1
