Number of 65+ in the US (millions)

• 1 in 5 people will be 65+ In 10-20 years…

• 1 in 3 people will be 65+ By 2050…

• Expect to live 19+ years If you reach age 65…

The Epidemiology of Healthy Aging

Lifespan: the average length of life in years

Lifespan is about living longer…

Healthspan: the period (in years) of one’s life that is generally healthy

Healthspan is about living better!

Pitfalls: “What goes wrong” (risk factors)

Pathways: “What goes right” (protective factors)

Things that threaten our capacity for healthy aging

Things that promote our capacity for healthy aging

Eat smart! Be active! Stay engaged!

After the disease or serious risk

factor, but BEFORE any symptoms

Manage long-term health problems

to maximize quality of life

Crash rate increases in drivers 60+ (uptick after age 80)

Crash rates still higher in 20-24 year old vs. 70-74 year old drivers

What does this mean?

Smaller % of all crashes Drive less reduce risk

↑ Crash rate per mile ↑ Fatality rate per mile

Mature Drivers…

Mature drivers present a lower risk to others…

But experience increasing personal risk of crash

This means…

What can we do about this? “Brain Training” can increase a person’s Useful Field of View (UFOV)

Benefits –Safer driving

–Maintained driving

–Better Health, lower health costs

–Reduced Risk for Depression

Concluding remarks • 65+ is the fastest growing part of society

• Healthy Aging is about…

– Increasing Healthspan, not just lifespan

– Prevention is key

• Preserve Cognitive Health

– Be active (or not sedentary)

– Stay socially and mentally engaged

• Driver Safety

– Crash risk increases as we age

– May be ways to improve safety/maintain

independence
