Humans age faster at the age of 44 and 60 years: Study

Human ageing is not a gradual process but occurs in at least two accelerated bursts at the ages of 44 and 60 years, a study said. The first wave of changes included molecules associated with Cardiovascular disease and the ability to metabolise caffeine, alcohol and lipids. The second wave involved molecules involved in immune regulation, carbohydrate metabolism and kidney function.
