Is Longevity Genetic?

Based on a study of thousands of twin pairs, only about 25 percent of the difference in lifespan
among people is genetically determined.

Stay tuned for the next video APOE—The Single Most Important Gene for Longevity ( ).

    I’m never going to like your “nose hair camera angle” /too close introductions on videos. Feels like you’re going to accidentally spit in my breakfast . Feels like I can smell the coffee on your breath-or green tea. Too close, too intimate. FFWD!

    2:33 – Wondering if this “incidence” is adjusted by age (i.e., has it been taken into account that people in Africa just don’t live as long and have a lower chance to develop cancer).

    “I don’t want to age!” I cried like Lucille Ball.

    Get off the couch or iPad and go outside.
    Walking, running, bicycles, escooters, green open spaces, electric buses, electric commuter trains and trams are all parts of a good transportation system. Speak up for improved transportation options in your city. Every train station needs safe, protected places to park and lock bicycles. Children and older adults should be able to ride bicycles to work, school or for fun safely. Stay active for as long as you can. There should be more options than getting into a car.
    Staying active as you age is a key factor. Electric bicycles are bringing many older adults back to cycling. Easier on hills and knees.
