Humans age dramatically at two key points in their life, study finds

Scientists have discovered that human aging occurs in two accelerated bursts: first at the age of 44, and then again at 60. A study followed 108 participants over several years to observe aging changes in their molecules. The study found that aging does not happen gradually but shows accelerated, non-linear changes at the ages of 44 and 60. During these periods, the ability to metabolize caffeine and alcohol decreases, and changes in proteins that hold tissues together occur. Disease risks also increase after the age of 60. Identifying these patterns can aid in disease prevention and management.
