The Curious Case of Cartilage: Ears and Noses
Perhaps the most well-known example of body parts that get bigger with age are the ears and nose. While they don't grow like they do during childhood, they do increase in size due to a combination of factors. The primary reason is that they are made of cartilage, a type of connective tissue that continues to grow and change throughout your life.
- The constant addition of new cartilage cells adds to their overall size.
- Gravity's effects over decades cause the soft tissues to lengthen and sag, contributing to the perceived increase in size, especially the earlobes.
- The connective tissues that support the nasal cartilage also weaken, which can cause the tip of the nose to droop and spread.
Internal Increases: The Prostate and Fat Deposits
Beyond cartilage, several internal tissues and organs can also enlarge with age, though these changes are not always benign. For men, one of the most common age-related enlargements is the prostate gland.
Benign Prostatic Hyperplasia (BPH)
Also known as BPH, benign prostatic hyperplasia is a condition where the prostate gland grows in size. This can press against the urethra, causing urinary issues like a weaker stream, a frequent urge to urinate, and difficulty emptying the bladder. This condition is very common, with the prostate potentially doubling in weight between the ages of 20 and 90.
Redistribution of Body Fat
Body composition shifts significantly with age. While the layer of fat beneath the skin (subcutaneous fat) may shrink, the amount of fat stored deeper within the abdomen, known as visceral fat, tends to increase. This redistribution can make the body appear wider in the middle, even if overall weight hasn't changed dramatically.
- Visceral fat is particularly concerning because it surrounds internal organs and is linked to a higher risk of heart disease, diabetes, and other metabolic issues.
- Hormonal changes, such as reduced testosterone in men and estrogen in women post-menopause, contribute to this shift in fat storage.
Bones and Other Structural Changes
Although many people experience a loss of bone density (osteoporosis) with age, which leads to shrinking in height, certain bones and structures can thicken. Research has shown that the skull can thicken over time, especially in the frontal sinuses. Additionally, bones in the ribs and femur may also grow slightly, and the pelvis can widen by a small margin.
What Gets Smaller with Age? A Comparative Look
To fully understand how the body changes, it is important to compare what grows with what shrinks. The reality is that more parts of the body experience atrophy than hypertrophy.
| Get Bigger | Get Smaller |
|---|---|
| Ears and Nose (Cartilage) | Lean Muscle Mass (Sarcopenia) |
| Prostate Gland (Men) | Bone Density (Osteoporosis) |
| Abdominal Fat | Some Internal Organs (Liver, Kidneys) |
| Skull and Pelvis (Minor) | Skin Elasticity (Collagen/Elastin) |
| Face (Jowls, Chin) | Subcutaneous Fat Layer |
Mitigating Age-Related Changes with Healthy Habits
While some physiological changes are unavoidable, lifestyle choices can significantly influence how you experience aging. Maintaining a healthy lifestyle can help you manage your body composition and mitigate the negative effects of muscle and bone loss.
- Regular Exercise: Engage in a mix of aerobic and resistance training. Weight-bearing exercises like walking or lifting weights help maintain bone density and muscle mass, combating sarcopenia.
- Nutrient-Rich Diet: Consume a diet high in fruits, vegetables, whole grains, and lean protein. Adequate calcium and vitamin D are crucial for bone health. Higher protein intake can help preserve muscle mass.
- Stress Management: Chronic stress can impact hormones and contribute to metabolic issues. Practices like mindfulness or yoga can help keep stress levels in check.
- Stay Hydrated: Proper hydration is essential for skin health and overall cellular function.

Conclusion: Embracing the Full Picture of Aging
The question, "What gets bigger as you get older?" reveals that the aging process is a complex tapestry of both growth and decline. While the nose and ears may lengthen and certain fat deposits increase, these changes are accompanied by the more significant and widespread loss of muscle mass and bone density. By understanding these diverse physiological shifts, we can move past common misconceptions and focus on proactive strategies that promote healthy, active longevity. Instead of fearing what changes, we can take control of our health to support our bodies as they evolve.
