Many people imagine that 80-year-olds are frail and ill, but that is not necessarily the reality, USA TODAY writes.
Researchers explain that genetics, lifestyle, and environment all play a major role in how people age.
Some individuals remain active and independent well into their 80s, while others experience more health problems.
Therefore, age alone does not provide a clear picture of a person’s health, according to information from Johns Hopkins Medicine and aging researcher Steven Austad, as reported by USA TODAY.

The body has to work harder
As people age, blood vessels often become less flexible. This means the heart has to work harder to pump blood throughout the body.
According to the Mayo Clinic, this can increase the risk of conditions such as high blood pressure and heart disease.
Bones and muscles also gradually become weaker. This can make it more difficult to maintain balance and increase the risk of falls and fractures.
Health experts therefore recommend regular exercise as well as adequate calcium and vitamin D intake, according to USA TODAY.

The most important changes occur in the brain
Many people find that their memory becomes less sharp with age.
Harvard Health states that the brain gradually shrinks over time, which can make it more difficult to remember names and small details.
However, research also shows that some people over the age of 80 retain a level of memory comparable to that of much younger individuals.
