Longevity is influenced by inherited factors, with estimates suggesting up to 50% of lifespan is passed through genetics. DNA does not fully determine aging outcomes because chemical changes can alter how genes function. Epigenetics links daily choices to the “switches” that regulate gene activity related to aging and illness. Cellular signs of aging can begin in the 30s, and earlier action can better protect health over decades. Practical routines can be used as a “health portfolio” to manage risk before symptoms appear. Changes such as stopping late-night snacking and increasing awareness of behaviors can support healthier aging.
"Good genes are one of the biggest factors in living a long, healthy life: up to 50% of longevity is inherited, new research suggests. Still, DNA doesn't have to be your destiny when it comes to aging and illness. Take Dr. Florence Comite. As an identical twin, she's seen firsthand how our unique life experiences can shape our health and, more importantly, what we can do about it."
"“By understanding all the factors that make up who we are and thinking of it as a proactive approach, you identify risk before symptoms, and you can stop it in its tracks and even reverse it,” she said of aging. “Being able to turn switches on and off by the choices we make is the way we can give the control back to ourselves,” she said."
"“We begin to show changes of aging below the surface at the cellular level in the 30s. And we can do something about it to really protect our health for life because the earlier we do it, the better off we're going to be,” she said. Comite shared some of the best health changes she's made to her own routine that you can add to your own “health portfolio” for a longer, healthier life."
"Ditch the bedtime snacks Comite said she saw major benefits after triumphing over her own personal health nemesis: the late-night snack. “I'm a grazer. At night, I would just sit and snack on fruit, chocolate, ice cream, whatever. When I gave that up, and I made myself aware of the fact that I just have to sto"
