While we are living longer, the quality of those extra years is a growing concern. Instead of enjoying vibrant later years, many face significant health challenges.

As of July 2025, the global average life expectancy is estimated to be [insert number]. This reflects a continued increase in longevity, despite a temporary setback during the COVID-19 pandemic. Developed nations with strong healthcare, sanitation, and healthy lifestyles boast even higher averages, reaching up to 84 years.

While lifespans have increased, healthspans—the years lived with good mental and physical health—haven’t kept pace. Failure to address this will impact individuals, families, and the care systems we rely on.

The traditional four-stage life model (youth, family, work, retirement) is outdated. We now experience five phases, with mid-life caregiving and extended later-life dependency placing new pressures on families and economies.

The modern life course now looks more like this:

  1. Youth (0–20): Education and early development
  2. Single and Working (20–30): Career-building with opportunities for personal enrichment through travel and new experiences.
  3. Family Formation and Caregiving (30–50): A period characterized by diverse paths, including raising families, nurturing chosen family units, or balancing career demands with eldercare responsibilities.
  4. Working with Dependent Parents (50–67): The “sandwich generation” increasingly supports both younger and older family members.
  5. Retired, Often Dependent (67–80+): Extended retirements, frequently marked by increasing physical and cognitive decline.

This shift from four to five stages has significant consequences. Mid-life adults face competing demands, often while managing dual-income households or living alone. Retirement, once brief, can now last decades, frequently with increasing dependency.

Support systems (social, economic, medical) are struggling to adapt. This creates a global healthspan gap, where increased longevity doesn’t equate to increased well-being.

The healthspan gap—and what it costs

Research indicates we are entering the greatest wealth transfer in history, from older to younger generations. However, much of this wealth may be consumed by healthcare costs.

Long-term care expenses, particularly without insurance or public assistance, can quickly deplete assets. Years of care can erase a lifetime of savings. Many families lack adequate financial protection, and public eldercare systems face increasing strain in aging societies.

If budget cuts occur, families may bear a greater burden, quietly diminishing inheritances.

We are not only living longer but also living longer with cognitive impairments like dementia and Alzheimer’s. Without action, this trend could worsen.

This is not a hypothetical scenario. It’s a real possibility if healthspan doesn’t improve relative to lifespan, and support systems fail to adapt.

The healthspan imperative

To ensure longer lives are truly better, we must prioritize improving healthspan, requiring new approaches to prevention, technology, policy, and planning.

First, prioritize prevention across all life stages, not just old age. Expand access to community wellness programs focused on movement, nutrition, and social connection. Emphasize preventive care early, with lifelong attention to cognitive and emotional health. Support flexible work and phased retirement to reduce caregiver stress.

Second, technology can help. AI assistants and robots can aid with mobility, medication reminders, and safety monitoring, promoting independence for older adults. AI tutors and robotic companions already support learning in families. Predictive tools and remote monitoring can detect early signs of cognitive, physical, or emotional decline, enabling timely intervention. These tools enhance, not replace, human care by boosting independence, extending capabilities, and lessening caregiver burden.

Public systems must also evolve. Governments should shift funding from institutional care to proactive, community-based models. Policies supporting aging in place, caregiver tax credits, and long-term care savings incentives can align care with current realities, especially as aging populations pressure public finances.

Finally, plan across generations. Families need support to discuss roles, responsibilities, and expectations before crises arise. Integrate healthspan into financial and estate planning, as our health directly affects what we leave behind. Caregiving, aging, and inheritance are interconnected and require collective input and support.

We are at a crucial point. If we allow longevity to progress without a plan, we risk dependency, family fragmentation, and generational loss. However, investing in healthspan early, equitably, and boldly can reshape the future.

We can safeguard the well-being of aging populations while ensuring financial and emotional security for younger generations. We can harness innovation to not just extend life, but enrich it. And we can cultivate communities that age with strength, grace, and resilience.

We’ve added years to life; now it’s time to add life to those years.
