Does NAD Really Help With Aging? The Science Behind the Longevity Buzz

By middle age, our bodies' levels of the vital coenzyme nicotinamide adenine dinucleotide (NAD+) can drop by as much as 50%, impacting crucial cellular functions. This natural decline has fueled intense research and marketing around supplementation, leading many to ask: **Does NAD really help with aging?**

Do people who work less live longer? The truth about work, stress, and longevity

According to a 2021 WHO/ILO study, over 745,000 deaths from heart disease and stroke in 2016 were related to working more than 55 hours per week. This powerful statistic gets to the heart of the matter: while the question **do people who work less live longer** might seem overly simplistic, the evidence points to a critical connection between a healthy work-life balance and longevity.

Does aging accelerate at 60? Understanding the 'Aging Bursts'

Recent research published in *Nature Aging* has challenged the long-held belief that aging is a gradual, linear process, suggesting instead that it occurs in significant "bursts". Scientists at Stanford Medicine and in Singapore found that dramatic shifts at the molecular level, including changes in molecules related to metabolism and immune function, happen most notably in a person's mid-40s and again at around age 60. This groundbreaking discovery directly answers the question, **does aging accelerate at 60?**, revealing that it is indeed a milestone decade marked by heightened biological changes.

Does rapamycin actually slow aging? What the science says

While animal studies have consistently shown that rapamycin can extend lifespan and healthspan, reviews of human trials reveal limited evidence to support these claims in healthy adults. The drug, originally an immunosuppressant, has become a focal point in longevity research for its ability to inhibit the mTOR pathway, a key cellular process linked to aging. However, the translation of benefits seen in mice and other organisms to humans remains uncertain and unproven.

How do I check my biological age?

While your chronological age is simply the number of years you've been alive, your biological age reflects your body's cellular health and how well its systems are functioning [1]. Understanding this distinction is the first step toward answering, "How do I check my biological age?" and gaining insight into your overall wellness.

Decoding the Complex Process: What is the main reason for old age?

Research indicates that genetics account for only about 20% of an individual's longevity, with the remaining 80% attributed to lifestyle and environmental factors. To understand **what is the main reason for old age**, we must look beyond a single cause and recognize it as a multifaceted biological process influenced by a complex web of interactions.

Is it theoretically possible for a human to live forever?

While the maximum documented human lifespan remains 122 years, scientists and futurists are actively exploring whether that limit is a 'glass ceiling' or a 'brick wall.' The question, "Is it theoretically possible for a human to live forever?", delves deep into our understanding of biological processes and the potential of future technologies.

What is the theoretical maximum human lifespan?

While average life expectancy has risen dramatically over the last century, the maximum human lifespan remains a topic of intense scientific debate. What is the theoretical maximum human lifespan, and does a hard biological limit exist that no amount of medical advancement can overcome? Research into the biology of aging continues to provide new insights.
