Are We Getting Worse at Ageing?

In 2025, 38% of the UK population fell into the "over 50" category. We are living longer than ever, but it begs the question: What is life expectancy if it doesn’t include "healthspan"? 

Does a longer life mean better health, or simply better medicine keeping us afloat? The truth is that our 50s are often a mirror held up to our 30s. The choices we make—like smoking in our 20s or neglecting strength—don't disappear; they manifest decades later.

The Biological Reality of Decline

Old age is frequently viewed as synonymous with declining health. It is closely associated with a cluster of conditions: cancers, arthritis, dementia, chronic renal failure, osteoporosis, sarcopenia (muscle loss), and atherosclerosis.

Nearly every organ system is impacted:

• Musculoskeletal: Loss of bone density and muscle mass.

• Endocrine & Metabolism: Hormonal shifts and a slowing metabolic rate.

• Cardiovascular: Stiffening of the arteries and reduced heart efficiency.

  
  

So, do we just accept this fate? Absolutely not.

A Timeline for Lifelong Habits

Healthy ageing is a compound interest project. The earlier you "invest," the greater the payout.

• Childhood: The Foundation of Habit This is where our "palate" and relationship with activity are formed. Neurobiology shows that habits formed in childhood—such as a preference for whole foods or daily movement—become the baseline "default" for the brain's reward system in adulthood.

• The 20s & 30s: Peak Capacity In these decades, you are still building peak bone mass and cardiovascular reserve. This is the time to build the "buffer" that your body will draw from later in life.

• The 40s & 50s: The Hormonal Shift This is a critical turning point, especially for women. Perimenopause and menopause trigger significant physiological changes. As oestrogen levels drop, the protective effect on bones and the heart diminishes. Nutrition advice must "switch up" here to focus heavily on anti-inflammatory foods and bone-supporting minerals.

  
  

The Nutrition-Exercise Connection

As you age, your body becomes less "efficient." You generally need fewer calories (as metabolism slows) but more nutrient-dense foods.

To avoid sarcopenia, increasing protein intake is non-negotiable. Without it, the body breaks down its own muscle to function, leading to frailty. Nutrition, however, cannot work in a vacuum; it goes hand-in-hand with exercise. Resistance training "signals" the body to use that protein to repair and maintain muscle and bone.

Lessons from the Blue Zones

If you want to see what "getting better" at ageing looks like, we look to Blue Zones—specific regions like Okinawa (Japan), Icaria (Greece), and Nicoya (Costa Rica), where people regularly live to 100 with their cognitive and physical health intact.

Their success isn't down to luck; it’s down to the Power 9 principles:

1. Move Naturally: They don't run marathons; they garden and walk throughout the day.

2. Purpose: Having a reason to wake up in the morning (what Okinawans call Ikigai).

3. 80% Rule: They stop eating when they are 80% full to avoid metabolic stress.

4. Plant-Slant: Their diets are predominantly whole-food and plant-based.

5. Social Connection: They belong to communities that support healthy behaviours.

   
   

The Bottom Line

We may not be able to stop the clock, but we can certainly change how we experience the time. By focusing on nutrient density, managing hormonal shifts, and adopting Blue Zone habits, we don't just add years to our life—we add life to our years.
