Livelong Weekend Pulse
Your weekly snapshot of the breakthroughs shaping how we live longer and better.
🔬 Can we actually slow down the aging of our cells?
That’s the question we explored in our latest Livelong session with Sebastian Conti of T.A. Sciences. His answer: yes — but it’s complicated.
Telomeres, the protective caps on the ends of our chromosomes, shorten each time cells divide. When they become too short, cells stop functioning properly or turn into inflammatory “zombie cells.” Telomere length is one of the strongest predictors we have of biological age and disease risk.
Key takeaways from Sebastian’s talk:
People with a high percentage of short telomeres face up to a 22x higher risk of cancer.
Meditation is one of the few practices that may actually lengthen telomeres — not just slow their loss.
Zone 2–3 training supports telomere health, while chronic overtraining may accelerate shortening.
🩸 A hidden test with big implications: The CMV titer blood test isn’t typically ordered in annual checkups, but it can reveal important clues about your immune resilience. If you’re interested in longevity-focused care, it’s worth asking your doctor about adding it.
Think of it as your health 401(k). Measure where you are, make small course corrections, and invest early — because once your telomeres are gone, they don’t come back.
