Economic realities of aging research l.jpg

Economic Realities of Aging Research

  • FY 2004 NIH Budget:

    • 10.3% Heart, Lung, Blood

    • 17.1% Cancer

    • 15.6% Infectious Diseases

    • 3.6%Aging

Why??

(1) People are seriously ambivalent about medically extending life


Why the ambivalence l.jpg

Why The Ambivalence?

  • The Fairness Argument

  • The Malthusian Argument (Resource shortages)

On the Other Hand…

  • We Don’t:

    • Encourage smoking

    • Renounce antibiotics and vaccines

    • Destroy insulin supplies

    • Reward reckless driving

    • Refuse to treat heart attack victims


A tactic scientific mistake l.jpg

A Tactic/Scientific Mistake:

Our Focus has Been on Length of Life


Slide14 l.jpg

Aging = Functional Loss Over Time

(after Nathan Shock)


Aging l.jpg

Aging =

  • Gradual and progressive loss of function over time, leading to:

    • Increasing incidence of death and disease

    • Decreased health and well-being*


Mission statement us national institutes of health l.jpg

Mission Statement:US National Institutes of Health

[Our]… mission is science in pursuit of fundamental knowledge about the nature and behavior of living systems and the application of that knowledge to extend healthy life and reduce the burdens of illness and disability.


Mission statement uk medical research council l.jpg

Mission Statement:UK Medical Research Council

To encourage and support high-quality research with the aim of maintaining and improving human health


What is health l.jpg

What is Health?

“Health is a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity.”

Preamble to the Constitution of WHO, 1946


What is health ii l.jpg

What is Health II?

Possessing the physical capability to do the activities in life that one wishes to do.

Why??

People are seriously ambivalent about medically extending life;

Aging has no built-in constituency of energized, grieving survivors


Slide25 l.jpg

Why??

People are seriously ambivalent about medically extending life;

Aging has no built-in constituency of devoted, grieving survivors

The naturalistic fallacy is common

The Way It Was(sources Lovejoy, et al.1977; Neel & Weiss, 1975; Gage, 1988)


Social expectations were based on short expectations of life l.jpg

Social Expectations Were Based on Short Expectations of Life

  • Richard II at 14 years old pacified Wat Tyler’s troops with a speech.

  • At 14, Alexander Hamilton set numerous rules for sea captains who traded with his employer’s firm.

  • Alexander the Great, a teenager at the time, led armies in battle.

  • A warrior’s young page might be made a knight at 12.

From Barzun, Dawn to Decadence* (2000),

* Published when Barzun was 93

Rationale for the effort to slow human aging l.jpg

Rationale for the Effort to Slow Human Aging

  • Goal is improvement and preservation of health, not (necessarily) the prevention of death

  • That goal is consistent with all disease-based biomedical research efforts

  • Continuing to increase longevity by disease-based advances alone could be a major catastrophe

    • 25 - 50% of people over 85 have disabling dementia

  • Slowing aging is a much more effective approach to preserving health than treating individual diseases
