Uncertainty is a reality
of life and nowhere is this more applicable than later life when people face
uncertainties about their health (will I get diabetes or dementia?), wealth
(will I outlive my savings?), and life expectancy (how long will I live?). This
post will describe three important spans of life.
Life span
is the length of time a person lives, from birth until death. Health span
is the portion of life spent in relatively good health, with physical and
mental ability to perform desired activities and maintain independence. Wealth
span is the period when people have sufficient financial resources to
support their desired lifestyle. These three spans are closely connected,
especially during later life.
Most people want all
three spans to be long. In other words, to live a long life (longevity) in good
health with enough money to support themselves. This outcome takes planning and
positive daily habits. Below are strategies to lengthen the three spans of your
life.
Life Span
People can support
longevity by avoiding tobacco, maintaining a healthy weight, eating a
nutritious diet, staying physically active, getting adequate sleep, managing
stress, receiving recommended preventive care, and maintaining meaningful
social connections. Regular medical and dental checkups are also important to identify
health problems early. Avoiding preventable injuries, particularly falls and
automobile accidents, also becomes increasingly important with age.
Health Span
Lengthening health span means
a longer period of healthy functioning. Strength training can help preserve
muscle mass, while aerobic activity supports cardiovascular health. Balance and
flexibility exercises may reduce fall risk and help people remain mobile. Cognitive
stimulation through reading, learning new skills, hobbies, and social
activities can support mental well-being. Also, managing chronic conditions,
taking medications appropriately, and addressing hearing or vision problems.
Wealth Span
Strategies include saving
consistently before retirement, avoiding excessive debt, maintaining an
emergency fund, diversifying investments, controlling spending, and developing
a sustainable retirement withdrawal strategy. Delaying Social Security, when
appropriate, can increase monthly benefits, while working longer can provide
additional earnings and allow retirement savings to grow. Retirees should also
plan for inflation, taxes, health and long-term care expenses, and longevity
risk.
The goal is not just maximizing
each span independently but aligning your health span, wealth span, and life
span. Successful aging is about more than adding years to life. It is
also about adding life to those years with good health and financial
resources to make later life enjoyable and meaningful. Remember, the greatest
wealth is health (Virgil, BC).
