Genetics
Genetics is one of the main factors that determine longevity. Long-lived species such as bowhead whales and squirrels have special traits that allow them to live for centuries; Human beings also possess this capacity for exceptional longevity.
Extreme longevity in humans is the result of complex gene-environment (GxE) interactions that have been widely investigated.
Research is uncovering genes that could explain why supercentenarians live so long, although the exact cause remains uncertain. A recent study published in Science has discovered that these genes are related to longevity depending on age and sex.
Environment
The environment is a vast system made up of interactions between living and non-living things on Earth. It covers the atmosphere, water, soil and all natural resources such as animals, plants, minerals and microorganisms.
The environment provides us with a wide range of goods and services essential to sustain human life. These include food from living organisms, energy for cooking and transportation, sunlight, water, oil, etc.
Lifestyle
Lifestyle refers to the way one lives one's life, from the type of clothes one wears and food choices to musical preferences. It reflects your values and opinions about the world around you.
Numerous studies have shown that a healthy lifestyle can extend your life. However, it is essential to remember that both genetics and environment play a role in determining life expectancy; Genetics usually account for 20 to 30% of longevity, while environmental elements make up the remaining 70%.
Stress
Stress is the body's response to perceived pressures. It alters almost all of our body systems, alters our way of thinking and feeling, which in turn can have detrimental effects on our health.
But the good news is that some stress can be beneficial and healthy. It trains us to respond to danger by activating our flight or fight systems and equipping us with tools to combat it.
Chronic stress can increase the likelihood of various health problems, such as mood disorders, digestive problems, headaches, a weakened immune system, difficulty conceiving, and high blood pressure. In addition, it contributes to premature aging by accelerating our biological clock - which accelerates the aging of DNA.
