The life expectancy of humans has increased in the 19th century by almost 35 years.
Significant contribution has been made by medical and technological progress. Infectious diseases and chronic diseases can be better treated by medicine.
The Frenchwoman Jeanne Calment was 122 years old, as old as nobody with proven documents.
Whether a person has reached or exceeded a limit of lifetime can not be clearly answered.
Experts argue that there is no reason that the increase in the maximum life span has reached its limit. The past has shown that formerly fixed age limits have been refuted.
Professionals argue that there are no genes that codify aging or the time of death.
But man’s physique gives biomechanical limits and is subject to natural wear.
It is important to know the different aging between the human brain and the body.
Nerve cells also die throughout life, resulting in the loss of around 10 percent of nerve cells.
When a person learns something new, the „plasticity of the brain“ causes new synapses to form or strengthen. As a result, brain regions can grow and expand even in old age. Old and unnecessary connections, on the other hand, become disconnected or weaker.
Humanity is working hard to extend life expectancy. A detectable upper limit is not yet in sight. But what matters is not the length, but also the quality of life.
