Tai chi may help look young

"To evaluate the potential life-lengthening effect of Tai Chi, we conducted a year-long, retrospective cross-sectional study comparing the rejuvenating and anti-ageing effects among three groups of volunteers under the age of 25 who engaged in either Tai Chi (TCC), brisk walking (BW), or no exercise habit (NEH)," said study corresponding author Dr Shinn-Zong Lin of the Center for Neuropsychiatry, China Medical University Hospital, Taichung, Taiwan. "We used young volunteers because they have better cell-renewing abilities than the old population and we also wanted to avoid having chronic diseases and medications as interfering factors," Lin said.
