When does ageing start?
In general, it can be said that ageing begins after the developmental phase at a time when the body is mature. In humans, this can be set at approximately the age of 20. This is the time when the classic signs of ageing become visible, such as the appearance of wrinkles or the decrease in performance and stamina. The speed at which each person ages can vary, mainly due to different environmental factors and the contribution of genetic predisposition. However, the general ageing processes responsible for ageing are probably the same for everyone.
