¿Cómo envejecerán las nuevas generaciones?

How will the new generations age?

The scientific advances derived from research and the chance to cultivate healthy habits allow people to imagine a different way of facing up to the start of their more mature years.

There were times, not so long ago, when anyone who had reached their fifties were considered to be an elderly person. Today, our society seems to be obsessed with reaching perpetual youth. But: is it really possible to face up to the years healthily, delaying the undesirable physical effects that we usually associate with old age?

In order to analyse this question, we talked to Tamara Pazos, a brilliant young scientist who studied for a Master in Neuroscience and who has written interesting books with titles such as Crecer sin envejecer (Grow without aging), Este Libro te hará vivir más (o por lo menos major) (This book will make you live longer (or at least better) and La biologia aprieta pero no ahoga (Biology pinches but it doesn’t choke) (all of them published by Paidós). In her opinion, the information we have available to us today gives the new generations the chance to age in a different way. Additionally, now we are seeing “a great research effort and investment in biomedicine, completely aimed at studying these cellular aging processes and illnesses associated with this.

 

Chronological age versus biological age

The first thing that we must consider is that the chronological age will unavoidably, continue to move forward, but the biological age will depend on how much we have looked after ourselves. “According to the context and the access to healthcare resources, there will be people who are seventy years old with a young, functional immune system, who are able to face up to and repair the damages derived from the passing of the years. And there will be other people who, due to an accumulation of stress, physical inactivity, environmental pollutants, lack of sleep, etc., who will have a deteriorated immune system that will speed up the aging process. The greatest differences will be found linked to the socio-economic status and the possibilities of access to these scientific advances,” Pazos explains.

 

A change of mentality

The science of longevity offers us a chance to change our mentality. “The idea is not to add years of life, but to add life to the years,” this researcher affirms. And she adds: “The science of longevity is showing us that aging is pliable and that we can influence how our immune system ages, which acts as the conductor for an orchestra of many other processes. A healthy immune system not only responds well to infections, it also keeps inflammation at bay which, when it becomes chronic, encourages cardiovascular, neurodegenerative or metabolic disease. Understanding this allows us to design specific strategies to help us to reach advanced ages in a better physical and mental state.

 

Four essential factors for a healthy longevity

Tamara Pazos is clear that the immune system must always be at the centre of the conversation about longevity. In order to look after this system, we must take the following four fundamental pillars into account:

  1. Movement: “Regular exercise trains immunity, improves the circulation of the defensive cells and reduces inflammation.”
  2. Rest: “Deep sleep is the moment when the immune system reorganises and repairs itself.”
  3. Diet: “Dietetic patterns based on vegetables, legumes, dried fruit and fish provide nutrients that regulate the defences and prevent their constant activation.”
  4. Social relations: “Isolation is one of the greatest accelerators of immunological aging, whilst social support protects it.”

Active aging

The commitment to active aging

It is very important to know which factors contribute to maintaining this essential physiological reserve that allows us to face up to our daily routine in spite of getting older.
