How easy it really is to turn the biological clock of life forward and backward has in fact only recently  been confirmed by Seong Jae  Kim and colleagues from the Northwestern University Feinberg School of Medicine and the Technology Evaluation Center of BlueCross BlueShield Association (Kim. 2013) Fast forward / backward, please! All the scientists had to do to make sure that the 29 healthy young (25.1 ± 4.1 years, M:F=8:21) and 16 healthy older subjects (66.5 ± 6.0 years, M:F=5:11) who participated in the sa...
