According to the World Health Organization, while age is the strongest known risk factor for dementia, it is not an inevitable consequence of aging. This raises the question: why do some old people never get dementia? The answer lies in a complex interplay of protective factors that foster cognitive resilience.
While centenarians still represent a small fraction of the global population, their numbers are rising substantially. In 2020, people aged 100 or older accounted for just 2 out of every 10,000 people in the US, according to a U.S. Census Bureau report from 2025. In this guide, we explore the odds of getting to 100 and the scientific factors that play a role.
While Alzheimer's disease is most commonly associated with older adults, a rare form known as early-onset Alzheimer's can affect individuals far younger. The earliest documented case involved a person in their teens, making the disease a concern across a much broader age range than commonly understood.
According to a large-scale study published in *GeroScience*, higher levels of total cholesterol in individuals over 65 were associated with a greater likelihood of reaching 100 years of age. The question of **do centenarians have high cholesterol** is complex, challenging traditional views on cardiovascular health and revealing a fascinating cholesterol paradox unique to the extremely old.
Statistically, for many in developed countries, the odds of living until 80 are higher than ever before. But what are the odds of living until 80 for *you*? The answer isn't a fixed number, but a dynamic probability that you have a surprising amount of influence over.
According to the U.S. Census Bureau, the centenarian population grew by 50% between 2010 and 2020, revealing that reaching triple digits is becoming less extraordinary. This trend raises a fascinating question: what are the odds of making it to 100 years old?
In 2021, an estimated 0.027% of the U.S. population were centenarians, according to UN data, showing that only a small fraction of people make it past 100. However, this number is on the rise globally, driven by improvements in healthcare, sanitation, and lifestyle. The likelihood of reaching this milestone varies significantly by region, genetics, and personal choices.
By age 30, most people reach their peak bone mass, after which bone density naturally begins to decline. Understanding **what causes your bones to age faster** is crucial, as this decline can accelerate due to various modifiable and non-modifiable factors, increasing the risk of osteoporosis and fragility fractures.
While the bulk of facial growth occurs during childhood and adolescence, studies have shown that facial skeletal changes, including those involving the cheekbones, continue subtly throughout life. The answer to **at what age do cheekbones stop growing** is not a simple cutoff, but a dynamic process that slows significantly after puberty, though minor changes persist into old age. This continuous process is influenced by a mix of genetics, environmental factors, and hormonal changes.
