Ageing is an inevitable phase of life that every human must go through, regardless of wealth, quality of life and unwillingness. Besides, the global population is ageing fast, and life expectancy has risen to 70 years and above in most countries. For the first time in global history, research done in 2020 showed that adults aged 60 and above outnumbered the number of children under five.
The remarkable improvements result from better nutrition, high-quality healthcare quality, improved sanitation and public health. The modern world has also brought better technological innovations, artificial intelligence and big data, among other related aspects that increase the life expectancy and ageing in the global population.
