While your birth certificate provides your chronological age, your body's true biological age is a much more accurate predictor of your overall health and longevity. In simple terms, biological age reflects the physiological state of your cells and organs, and knowing **how to calculate body age** can empower you to make informed decisions for a healthier future.

According to a Brigham Young University study, adults engaging in regular, high-impact exercise can exhibit telomeres indicative of cells nearly nine years younger than sedentary individuals. So, **does a fit body make you look younger**? The compelling scientific evidence confirms that physical fitness provides numerous biological benefits that directly combat the visible signs of aging.

Experts suggest that around age 25, the body’s natural collagen production begins to decrease by about 1% annually, prompting the question: do you start ageing at 25?. This subtle shift marks the onset of cellular changes that will eventually become more noticeable, though your biological age is not the same as your chronological one.

In a recent human trial involving adults over 50, participants who received therapeutic plasma exchange (TPE) saw a reduction in their biological age, with some combinations showing an average reduction of 2.6 years. These compelling, yet preliminary, findings have ignited a major discussion: **could plasma exchange therapy actually help you live longer?**

While diet is considered a single, leading predictor of chronic disease risk, it's part of a larger picture when asking: what is the strongest indicator of health? The reality is complex, involving numerous factors that, when taken together, offer a more complete assessment of overall well-being and longevity than any single metric alone.

Experts have developed numerous methods to estimate biological age, recognizing that chronological age is an imperfect measure of the aging process. A **body age estimation** is a metric that assesses your body's functional status, often revealing how genetic and lifestyle factors influence your overall health and longevity.

Did you know your biological age, a reflection of your body's cellular health, can differ significantly from your chronological age? Understanding how to check your body's biological age is the first step toward gaining valuable insights into your health and longevity.

Scientists have developed 'epigenetic clocks' that can estimate a person's biological age by analyzing changes to DNA. While doctors cannot know your exact chronological age without documentation, they can assess your body's true age, providing a deeper answer to the question: can doctors tell how old you are?

In recent years, the market for longevity and biological age tests has exploded, with one recent study finding that a single blood sample sent to different companies yielded biological age estimates varying by over a decade. This stark inconsistency raises a crucial question: Are longevity tests accurate, and what do the results really mean for your health? This guide explores the science, limitations, and practical takeaways from these popular tests.

While the term 'chronological disease' is not a recognized medical diagnosis, research shows that nearly two-thirds of global deaths are related to age-associated conditions. This phenomenon highlights a key distinction between a person's actual age in years and the biological processes that influence health over time. Understanding this is vital for promoting healthy aging and separating medical myth from reality.
