You can’t do anything about aging or some aspects of memory, but you don’t have to surrender to memory decline.

What are they? They include exercising, eating healthfully, getting good sleep, socializing, and challenging our mind. And there are some memory tricks anyone can learn.

Come as you are: The “all are welcome” ethos at Burning Man has a specific meaning for members of the Mobility Camp, a volunteer-led group that makes camping at the festival more accessible. Above, some members roll through the grounds as “Lamplighters,” providing illumination to help people return to their camps after sunset. “Humans need to have adventure and love, so the wheelchair Lamplighters will keep carrying our lanterns,” said one of the first illuminators to use a wheelchair.
