Only 20 percent of our longevity is genetically determined. The rest is what we do, how we live our lives and increasingly the molecules that we take. It's not the loss of our DNA that causes aging, it's the problems in reading the information, the epigenetic noise.
Interpretation
Our lifespan is largely influenced by our lifestyle and choices rather than just genetics.
David Andrew Sinclair emphasizes that while genetics play a role in how long we live, the majority of our longevity is determined by our lifestyle choices and external factors. This perspective highlights the importance of healthy living and the impact of environmental influences on our biological processes, particularly the epigenetic factors that affect how our genes operate.
In practice
In a speech about healthy living, one might quote, 'Only 20 percent of our longevity is genetically determined...' to emphasize personal responsibility in health.
We used to think that aging was a lot like, as if we were cars made fresh and youthful and then we've entered this breakdown in diet. What we didn't realize until recently is that we're much more complex than a car. We fix ourselves if we're broken.
As we get better at reversing aging it will be possible to take one medicine and within weeks feel and even look younger. Imagine going to a doctor to get a pill for diabetes, and this same medicine will prevent heart disease, Alzheimer's, cancer, and will give you more vitality too.
If I'm not hungry and I'm busy, I am quite happy to skip a meal. It's informal intermittent fasting. I feel strongly that this is one of the strongest areas of longevity research.
So what we're all hoping to do, us researchers, is to develop ways to not really just extend lifespan but to keep people healthier for longer. We may just have a greater impact than a single drug because these drugs could potentially treat one disease but prevent 20 others.
I thought that tackling aging and the mechanisms that promote life would be worth figuring out. I wanted to learn why it is that some people are healthier than others and why some people live to 110 and others only to 60 or 70.

Scepticism is as important for a good journalist as it is for a good scientist.
Supervised learning works so well when you have the right data set, but ultimately unsupervised learning is going to be a really important component in building really intelligent systems - if you look at how humans learn, it's almost entirely unsupervised.
It is possible in medicine, even when you intend to do good, to do harm instead. That is why science thrives on actively encouraging criticism rather than stifling it.
A review of seventy-four clinical trials of antidepressants, for example, found that thirty-seven of thirty-eight positive studies [that praised the drugs] were published. But of the thirty-six negative studies, thirty-three were either not published or published in a form that conveyed a positive outcome.
Evolution is one of the two or three most primally fascinating subjects in all the sciences.
