Only 20% aging from genes
The insight from the snip is that only 20% of aging is determined by genetics, while 80% is influenced by external factors and lifestyle choices. The balance between oxidation and antioxidants plays a crucial role in this process, with free radicals being a normal byproduct of bodily processes and external factors. This understanding contradicts the previous belief that aging was mainly due to free radicals. The concept of epigenetics highlights the control individuals have over how quickly they age and how they look as they get older, without the necessity of surgical or cosmetic interventions.
