Aging—it is upon
you and me as we accrue weeks and months, one day at a time. The length of time we can expect to live is
increasing as well. According to the US Census Bureau,
Americans are living nearly double
the years we were a century ago.

WHY are we living longer?
Living longer can be attributed to many social and medical
advancements since the 1900’s, including
embracing the germ theory, discovering antibiotics, implementing vaccinations, and
improving water treatment and sanitation.
Diseases that maimed or killed our progenitors, like cholera,
tuberculosis, polio, measles, and the mumps, are now treatable and avoidable. Living
longer is great news, right?
Living longer, but at
what cost?
We are all aging at different speeds and with different
results. Just
look around you---you have seen 90-year-olds who look like they’re
70, and 65 year olds who look like they’re 80.
These differences can be attributed to a web of factors:
genetics, environmental influences, exposure to toxins, dietary nourishment,
occupation, stress, and co-morbidities, to name a few. Some of these factors we can change, others
we can’t. Unfortunately for some people, living longer means being sicker with
chronic and multi-morbid conditions.
Baby Boomers: Wealthier and Wiser
Boomers, the largest cohort entering old age currently, are
predicted to live longer than previous generations. More Boomers live in non-traditional home
environments, have spent more time in the workforce due to the economic
downturn of 2007, have more savings, use more electronic technology and are
savvy with cell phones, tablets and computers (Sugar, 2014). They were of age in the Vietnam War and
watched women’s and civil rights unfold.
Due to their life experiences, Boomers are redefining what aging means
and are challenging us to think about aging in different ways.
And the U.S. government and scientists are responding,
working on ways we can age better and look forward to healthier futures with
the years we have left.
Paradigm Shift
2: Precision Medicine and Aging
Paradigm
Shift 1: Healthier Aging Now and in the Future
The government and providers are serious about stimulating
the public health conversation. A
paradigm shift in the last twenty years has turned America from a disease-treating
nation to a health-promoting, disease-avoiding nation with the advent of the government’s
initiative Healthy People 2000, 2010, and 2020.
The Affordable Care Act emphasizes
access to care for everyone,
making sure that as we age, we receive medical support across the
lifespan. In addition, national
governmental research entities, like the National
Institute on Aging, are allocating research dollars towards understanding diseases
of aging, like Alzheimer’s
disease.
With changes to affordability and accessibility, the aging
landscape is changing for the better. A
paradigm shift means thinking about aging in new ways. Researchers are primed to try new approaches.
What
the future looks like: Expect to see
more research results guiding aging strategies.
Think genetic and specific: precision medicine is medical
strategies for the individual person. Precision
medicine avoids a one-size-fits-all approach to aging, taking in to account
your genetic make-up and the specifics of your aging process. In 2016, President Obama announced
the paradigm shift toward precision medicine with the Precision
Medicine Initiative, pledging research dollars to accelerate progress
toward precision treatments. We are all
uniquely aging, and precision medicine will help us age better by:
·
Screening for your genetic disease risk—catch it
before treatment is needed
·
Treatment plans specific to your body’s genetic
code
·
Medications dosed at your therapeutic
level—treat to your threshold of appropriate responses
·
Targeting tumors and killing them quickly and
efficiently—treat precisely what needs targeting
An invitation has been extended to participate in precision
medicine research offered through the All of
Us initiative, sponsored by the National Institutes of Health. The goal is to have one million participants’
data gathered “to accelerate research and improve health.” This will go a long
way toward helping us understand issues associated with aging.
Paradigm
Shift 3: Team Science and Aging
We are better together.
In the past, researchers worked in isolation to solve problems. However, the new approach in research is
using Team Science. Team
science is a paradigm shift that harnesses the collaborative powers
of researchers across disciplines to tackle sticky, complex, multi-factorial
problems. The increasing internet
abilities harnessing Big Data has
enabled this shift to occur. Working on
ubiquitous problems common to humankind just got easier. The realities of this
are that researchers can connect with like-minded researchers around the world,
and the power of their studies to benefit us has increased.
The aging-well paradigm lends itself to a team-science
approach, as stakeholders collectively put their minds toward helping people
feel, act and live better. Innovative research strategies, like Patient Centered Research approaches, listen
to aging people’s concerns and suggestions while designing research
projects. As older adults become more
involved in research, outcomes will be strengthened and benefit older adults
throughout the world.
What
the future looks like: Researchers,
aging adults, doctors, nurses, physical therapists, economists, psychologists,
sociologists, insurance companies, healthcare systems and others, combining
efforts to design research strategies to improve aging’s future landscape. What can you do? Get involved in aging research in your area.
Health Technologies:
Various Kinds and Purposes
In the last decade, the technological explosion has
populated our world with devices and apps.
Technologies provide real-time information about what we do and when we
do it. For those aging, electronics are powerful tools that can:
- · Remind us when and what to eat
- Monitor our movements
- Encourage us to exercise
- Track our intake and output
- Notify of a fall or life threatening cardiac rhythm
Challenges
to consider: How do we help aging adults tap into the power of gadgets, apps,
and electronic health information to promote their health?
Another exciting development with advancing technology is the
field of regenerative medicine. Previously when bodily function was lost due
to aging or disease, there was no recourse.
However recently, 3-D bio printing is allowing us to manipulate
materials in order to bio-print tissues and structures for the human body (Murphy & Atala, 2014).

Bladders, cartilage, and skin have been successfully
printed, and the capabilities are growing exponentially. For the aging adult, bio-printing offers new
vistas for degenerating body parts thereby prolonging functionality. The future is brighter for some diseases as
this capability grows.

What Can You Do?
Aging is a complex process.
While researchers are helping delineate many aspects of aging, there are
things we can do to help ourselves. Reichstadt
et al. (2010) identified ways we can psychologically age better, including
staying involved in a range of activities to engage in life, purse novel
activities, connect with family and friends, and generate social interactions. Gerontologist
Judith Sugar (2014) notes additional strategies to stay physically
heathy while aging:
- Consistently exercise with non-weight bearing and weight bearing activities
- Eat a variety of foods
- See your doctor for routine care and worrisome symptoms
- Decrease your levels of stress
- Sleep well
Start Early, Be
Involved
What does this mean to you and me? None of us is getting any younger, yet there
is so much we can do to age better than we are.
- Actively buy in to the aging-well paradigm.
- Take advantage of precision medical strategies that are increasing exponentially.
- Let technology assist you with devices and prompts to eat well, move more, and stay informed.
- Get involved in the aging research.
