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.
If an elderly but distinguished scientist says that something is possible, he is almost certainly right; but if he says that it is impossible, he is very probably wrong.
What we can be scientifically certain of is that our continued use of fossil fuels is pushing us to a point of no return
As our own species is in the process of proving, one cannot have superior science and inferior morals. The combination is unstable and self-destroying.
You stop planetary exploration, those people who do that extraordinary work are going to have to go do something else.
As a scientist, I want to go to Mars and back to asteroids and the Moon because I'm a scientist. But I can tell you, I'm not so naive a scientist to think that the nation might not have geopolitical reasons for going into space.
I give them experiments and they respond with speeches.
