Most people think aging is something that happens later.

In reality, the processes that determine how you age — and whether you stay functional — start decades earlier.

In this episode of Return on Health, we sit down with Roberta Vella Azzopardi, a geriatrician and geroscientist with a PhD in cognitive frailty, to break down what aging actually looks like in clinical practice.

Instead of focusing on single diseases, this conversation zooms out: Why do people lose independence? What really drives decline? And where are the biggest missed opportunities in prevention?

What this episode covers

• Why modern medicine often intervenes too late
• What frailty really means — and why it matters more than age
• How loss of muscle drives metabolic and cognitive decline
• The concept of peak span and why function beats lifespan
• Why hearing loss is one of the biggest overlooked dementia risk factors
• The massive gap in menopause and women’s health care
• What actually works vs. what’s just hype in longevity

Key takeaways

Frailty is best understood as loss of physiological reserves.
When those reserves drop below a certain threshold, even small stressors can lead to long-term decline.

This is why two people at the same age can look completely different clinically — one independent, one dependent.

A major driver of this process is muscle loss.
Muscle is not just about movement. It directly affects metabolic health, insulin sensitivity, and even brain function. The good news: even later in life, resistance training and sufficient protein intake can still improve outcomes.

One of the most underestimated risk factors discussed in this episode is hearing loss.
It contributes to cognitive decline through increased cognitive load, social isolation, and shared vascular mechanisms — yet remains widely underdiagnosed and undertreated.

Another critical blind spot is women’s health, especially around menopause.
Many symptoms are treated in isolation instead of addressing underlying hormonal changes, leading to years of missed intervention opportunities.
