It’s a matter of fact, thanks to scientific and technological innovations today we are living more and better.
But these changes have helped over the years also some genetic mutation, for example just think of the stature, with the new generations taller than their ancestors, or to the reduction of the fertility, because evolutionarily not the same need to reproduce ourselves as in the past.
But looking more closely to the evolution of the species, I have noticed, as many experts also say, that with the longer expectation of life and from age to age, it also have been acquired a lengthening of the time necessary for children to become “mature” or adults.
From long in many countries, the eighteen years of age represent the achievement of legal age, the coming of age linked with maturity, and this should suppose an eventual physic and mental maturity.
In the past, before age 18, a teenager was already considered an adult man, as evidently he already showed a physical and mental adulthood. Once, for a young man twenty years old, it was normal to be married, having children and already with a professional activity, beyond the need to cut definitively the “umbilical cord”, which kept him still tied to the family.
Today, instead, it’s not unusual for men older than 20 years still act and look like teenagers!
I would venture to say that the 18-years-old of sixty years ago can be compared roughly with the 25-years-old of today, about the look or the manhood, at least.
An evolutionary gap of 6-7 years or the price to pay for a greater longevity?
