Yes, and no. Let me explain. Aging is real, no one is questioning that. Over time, the body becomes less efficient, accumulates wear and tear, requires better maintenance, higher quality nutrition for proper function, etc. In the short term, think human lifespan, you can maintain good health, vitality, mobility, and immune function up to a certain point, and yes, you can get there with lifestyle and nutrition. Plenty of healthy or relatively healthy and highly active elderly populations can be found around the world. None of which are ravaged by either the diseases of civilization or infectious diseases. We refer to it as healthy and graceful aging. Ask yourself this, why some elderly populations are healthier than others and live longer as a result? Luck? Genetics? Or something else?

Of course, you cannot cheat the maximum cellular clock that your body possesses. But on the other hand, how do you think that happened that homo sapiens can live up to 120 years old while other primates cannot? Other primates' lifespan ranges from 20 to 45 years. Why is that? Magic? Why do some mammals have a similar lifespan to humans, and some exceed it, even to 200+ years? What is the reason for that? The answer starts with lifestyle and nutrition, which influences cellular repair, maintenance, recycling mechanisms amongst hundreds of different biochemical processes. Do you think that our species always had a lifespan setpoint at ~120 years? Or maybe we somehow got there during the long-term evolutionary timeframes? How did we get there? With nutrition and thriving as a species. Nutrition is what drives the entire immune system. In fact, it drives our entire biological machinery, including regulation, proper function, and proper response of the immune system against both viral and bacterial infections. Although we cannot extend our lifespan significantly, we can impact our cellular clock in the short term, and if the same behavior is to be repeated by further generations, the lifespan of our species will be extended. But for it to happen, we need to provide our bodies and biological machinery with everything it needs to keep proper function and to maintain health as long as possible. The species simply needs to thrive from a health and nutritional standpoint for that to happen. One caveat, though. We need to do all of this in a reproductive timeframe, so all the changes, adaptations, and optimizations are passed onto the next generations. This is the only logical explanation, an Ockham's razor which most traditionally "trained" and "educated" people do not understand. This is why el gato malo is wrong in his assumptions about aging, senescence, and risk stratification based on age. This is where math fails people like him because they do not understand that their data is incomplete (garbage in), leading them to false conclusions (garbage out). Everyone ignores lifestyle and nutrition when it is literally the deciding factor in immune function, influencing disease susceptibility, impact, severity, survivability, healthy aging, and lifespan. What is even worse, people have no idea what health is and what healthy foods and healthy nutrition are for our species. But that is for another talk...
