The quest for longevity has become a booming industry, with a plethora of products and services promising to slow down the ageing process. But what does the science actually say? In my opinion, the key to a long life is not found in the latest fad or the most expensive supplement, but in the simple, often overlooked, aspects of our daily lives. Personally, I think that the longevity scientists I interviewed at the Longevity Summit in Dublin have the answers we're looking for, and their message is both boring and brilliant. From my perspective, the consensus is clear: lifestyle changes are the most effective way to extend our healthspan and lifespan. What many people don't realize is that the miracle pill or injection is still a distant dream. In fact, the harsh truth is that we currently have no drugs or supplements proven to increase healthspan or lifespan. This is not to say that there is no hope; on the contrary, the good news is that we have the power to make a difference. The biggest myth, according to Dr. Matt Kaeberlein, is the belief that we can't do anything about how we age. In my view, this is simply not true. There’s lots you can do, and, as far as we can tell, there doesn’t seem to be a point of no return. It’s not too late to start. One of the most fascinating insights I gained from the summit was the importance of muscle mass. As Kaeberlein pointed out, muscle mass is under-appreciated, and we need to make sure we maintain it as we get older. This is a simple yet powerful message that can have a massive impact on our health. Another key takeaway was the importance of social connections. The evidence is clear: those with stronger social ties are more likely to live longer. This is not a new finding, but it bears repeating, as it is often overlooked in the pursuit of individual wellness. From my perspective, the one rule that separates science from sales is the need to measure and test. As Dr. Rozalyn Anderson put it, we need to weigh each animal down to 0.1 of a gram to decide how much drug to give them. For humans, this is a much more unsophisticated approach, and it's a detail that I find especially interesting. What this really suggests is that we need to be more mindful of our individual needs and not simply follow a one-size-fits-all approach. One of the most striking aspects of the summit was the criticism of the IV drips and peptides that are currently being sold as miracle cures. As Kaeberlein and Verdin pointed out, there is no compelling reason to believe that these products will have significant benefits for us as individuals. In fact, Verdin went so far as to call IV infusions medical scams in a white coat. This raises a deeper question: how do we separate fact from fiction in the world of biohacking? In my opinion, the answer lies in critical thinking and a healthy dose of skepticism. Before we let anyone influence what we put in our bodies, we need to ask the obvious questions: what’s their credibility, their expertise, and have they lied to you before? The future of longevity research is exciting, and it's clear that we are making progress. As Steve Horvath pointed out, the exciting part is actual human clinical trials, where we can measure whether something works in people while they’re alive to benefit. However, it's important to remember that the unglamorous truth is that mortality is still at 100%. But how we age is not inevitable. That trajectory of ageing can be changed, and anyone with an inclination to change what they’re doing, go for it. There’s a pretty good chance it’s going to work. In conclusion, the key to a long life is not found in the latest fad or the most expensive supplement. Instead, it's in the simple, often overlooked, aspects of our daily lives. Sleep, move, lift something, eat well most of the time, see your friends, and get tested before you buy anything. Nobody can put a discount code on any of it, which is precisely why nobody is selling it to you. The powder salesmen will tell you it’s more complicated than that, but the people who study ageing for a living told me it’s simpler - and mostly free.
