If there is one characteristic each of us shares, the world over, it is that we are aging! The World Health Organization estimates that the population of adults over the age of 60 will increase from 1 billion in 2020 to 2.1 billion in 2050 (2022). Life-expectancy trends continue to rise and people living into their 100s are not as uncommon as what it once was. With luck, living many years will result in countless positive outcomes, but it will certainly not be without its challenges either.
