It is true that the ears and nose can appear larger as we age. This is due to changes in the skin tissue and cartilage tissue over time. As we age, the skin loses elasticity and firmness due to a decrease in collagen and elastin, which can cause the ears and nose to appear more prominent in relation to the face. In addition, the cartilage tissue can also undergo structural changes that contribute to this effect.

Changes in the face

Yes, many people experience changes in their face as they age. Some of these changes include:

1. **Wrinkles and Expression Lines:** As we age, the skin loses collagen and elastin, becoming less firm and more prone to wrinkles and expression lines.

2. **Loss of Facial Volume:** Loss of facial fat and subcutaneous tissue can result in sunken areas and loss of volume in some parts of the face, such as the cheeks and the area around the eyes.

3. **Sagging Skin:** Decreased skin elasticity can lead to facial sagging, especially around the chin and neck.

4. **Double Chin:** The accumulation of fat and sagging skin in the chin area can result in the formation of a double chin.

5. **Changes in Cheekbones:** Cheekbones may appear less prominent due to loss of fat and sinking of facial tissues.

6. **Enlarged Pores:** Over time, your skin’s pores may appear larger due to decreased elasticity and increased sebum production.

These changes are a natural part of the aging process and can vary from person to person, depending on genetic factors, lifestyle and sun exposure, among other factors.

Effects of age on the human body

Aging affects the entire human body and can manifest itself in many ways. Here are some of the common effects of aging on the human body:

1. **Musculoskeletal System:**
– Loss of muscle mass (sarcopenia).
– Decreased bone density (osteopenia/osteoporosis).
– Joint stiffness and reduced flexibility.
– Increased risk of falls and fractures.

2. **Cardiovascular System:**
– Reduction in the elasticity of the arteries.
– Increased blood pressure.
– Decreased ability of the heart to pump blood (decreased cardiac output).
– Increased risk of cardiovascular diseases, such as hypertension, coronary artery disease and stroke.

3. **Respiratory System:**
– Reduction in lung capacity.
– Decreased function of respiratory muscles.
– Higher incidence of respiratory diseases, such as chronic bronchitis and emphysema.

4. **Nervous System:**
– Decrease in the number of nerve cells and the connections between them.
– Reduction in cognitive processing speed.
– Increased risk of neurodegenerative diseases, such as Alzheimer’s and Parkinson’s.

5. **Sensory System:**
– Decreased visual and auditory acuity.
– Reduction of smell and taste.
– Higher risk of eye problems such as cataracts and macular degeneration.

6. **Endocrine System:**
– Decreased production of hormones, such as estrogen, testosterone and growth hormone.
– Changes in metabolism, such as decreased basal metabolic rate and increased insulin resistance.

7. **Immune System:**
– Reduction in the effectiveness of the immune system (immunosenescence).
– Greater susceptibility to infections and autoimmune diseases.

These changes are part of the natural aging process and can vary from person to person. A healthy diet, regular exercise, stress management, and healthy lifestyle habits can help mitigate some of the negative effects of aging on the human body.
