Midlife refers to the middle years of life or middle age, which ranges from approximately age 40 to age 65.
Although there are different ways to classify this population, some studies have classified elderly adults between the ages of 65 and 74 years as youngest-old, those between ages 75 and 84 years as middle-old, and those aged over 85 years as oldest-old [5].

The American Psychological Association defines "middle adulthood" as beginning at 35 or 36, and many ranges do not end until 60 or 65. The Lancet considers midlife as starting from around age 40. Modern social scientists generally agree that midlife begins around 35 to 40 and ends around 55 to 60.
An older person is defined by the United Nations as a person who is over 60 years of age.
Australia's population has grown older, with the median age increasing from 32.4 years at 30 June 1991 to 38.2 years at 30 June 2021. Along the age distribution, the 30–39 age band are the largest cohort (see Demographic snapshot 2020–21).

Natural changes happen in the body as we age, such as skin damage from sun exposure, loss of muscle and physical strength, loss of some sight and hearing, as well as changes to our sleep patterns, energy levels and appetite.
The average difference between our actual age and how old we mentally feel is 12 years, but the gap changes across our lifetime. A 30-year-old typically feels two years younger mentally, while a 40-year-old feels eight years more youthful in their mind than what's written on their birth certificate.
Natural aging
As we mature, some physical skin changes occur naturally: Collagen production slows down – so skin loses its firmness. Elastin production decreases – and skin becomes less elastic. Fat cells start to disappear – and skin starts to sag.
