Though enormous resources are involved in research dedicated to the development of therapies against almost all age-related diseases, each field's potential success would not dramatically change the human population's lifespan. According to the Taeuber paradox, if all cancer in the world is cured, a human will leave on average only three years longer and six years longer if we fix all the cardiovascular diseases.
A growing number of scientists and pharmaceutical experts believe that a much more promising strategy is to solve the underlying cause or risk factor of all these diseases — aging.
Aging is a significant and continuously growing burden on economies and societies and the most critical risk factor for disease, disability, and mortality worldwide. Between 2015 and 2030, the number of people in the world aged 60 years or over is projected to grow by 56%, from 901 million to 1.4 billion, and by 2050 the global population of older people is projected to more than double its size in 2015, reaching nearly 2.1 billion.
Globally, population aged 60 or over is growing faster than all younger age groups
