If genes are like musical notes, epigenetics is the score that determines how these notes are played. In other words, epigenetics studies the mechanisms that regulate gene expression, without altering the DNA sequence.

How Epigenetics Affects Longevity

• Epigenetic Modifications: Environment, lifestyle, nutrition and stress can make epigenetic changes to our DNA, turning certain genes on or off.
• Cellular Aging: As we age, epigenetic modifications accumulate that can accelerate the cellular aging process and increase the risk of age-related diseases.
• Longevity and lifestyle: A healthy lifestyle, rich in physical activity and a balanced diet, can counteract the negative effects of epigenetics on aging, promoting greater longevity.

Epigenetic inheritance

An interesting aspect of epigenetics is its potential heritability. Some epigenetic modifications can be passed on to subsequent generations, influencing the health and longevity of descendants. This means that the life experiences of our ancestors could have an impact on our health.

A concrete example:

Imagine two identical twins, with the same DNA. Raised in different environments, one with a healthy diet and one with unhealthy eating habits, they could age very differently. Epigenetic modifications, induced by different lifestyles, could lead to significant differences in their health and life expectancy.

Epigenetics teaches us that our destiny is not only written in our genes, but is also shaped by our life experiences. Understanding epigenetic mechanisms allows us to actively intervene in our health and promote healthy longevity.
