It's about time we recognize the power of the arts in our fragmented society! Surely anthropologists already have noted that aging in other cultures is less isolating and that societies that integrate arts into their daily life have better outcomes for later life.
But how to convince institutions and individuals to try art? This is a problem, but a problem artists can help with. We can learn to adapt techniques of art making to whatever level is needed by beginners and people with lessened capacities. And as soon as artists are asked to do this, and given jobs that pay well enough for them to do it, we will improve the quality of life of our seniors.
