|By 2050 2 billion people will be over 60 years of age. The world's population|
instead of levelling off at around 9 billion by 2050 will now reach 10.1 billion people by 2100 and still growing. United Nations.
Not that I expect to live to the year 2050. I'd be 100 years old, but you might...
In most parts of the world, people are living longer. Life expectancy has risen by two decades since 1950. That is
5 hrs. or more everyday that we live.
You can expect to live to 76 yrs. of age
providing you are healthy.
Fertility rates are dropping. From 5 children in 1950 to 2.5 children today.
Population Rapidly Ageing
As you all know the world population is rapidly ageing. By the year 2050 the proportion of the world's population over 60 years of age will double from about 11% to 22%. That's an increase for 605 million people to over 2 billion. That's a lot of old people. In those same fifty years, there will be 400 million people 80 years of age or older. Quadrupled what it is now.
Coincidentally, never before in history will the majority of middle-aged adults still have living parents.
Low and Middle Income Countries likely to grow the Quickest Ageing Population
By the year 2050, 80% of older people will live in low and middle income countries, like Chile, China, and the Islamic Republic of Iran. The number of old people in Africa will grow from 54 million to 213 million.
Main Health Burdens by 2050
The main health burdens by 2050 for older people are from noncommunicable diseases, like heart disease, stroke and lung disease. The greatest causes of disability will be visual impairment, dementia, hearing loss and osteoarthritis. Older people in low and middle income countries carry a greater disease burden than those in rich countries. Three times as much. Many of these problems are already easily and cheaply preventable.
Strains on the Health Care System
People who no longer can look after themselves will quadruple.
Long-term care, home-based nursing, community, residential and hospital-based care is on the rise. Most training for health professionals does not include instructions to deal with age specific health conditions. WHO maintains care givers be trained on ageing issues.
Age-friendly environments can have a big impact on improving the active participation and independence of older people. Healthy ageing starts with healthy behaviours. Food, activity, smoking, alcohol, and toxic substances are all contributors.
*someone gives up smoking between the ages of 60-75 decreases the chance of premature death by 50%.
We need to break stereotypes for the ageing in the 21 Century.
There is some hope. New anti-ageing technologies, memory-enhancing drugs, to high tech joint replacements are on the horizon if not already here. Not to mention better diets, and healthier life styles.
