Why do more and more middle-aged people love photography?

Mainly now that ordinary people have a good life and have leisure time, it is not a problem to buy a camera and a few lenses, especially those who have just retired. In order to enrich their spiritual life, photography is a good activity. They should learn color, composition, light and shadow, camera control and computer retouching to improve their cultural quality. At the same time, they should use their brains to slow down aging, prevent Alzheimer's disease, run outside every day and keep healthy.
