In the current issue of Neurology , a group of researchers from China, led by John Y.J. Wang,1 posed just such a question. Their results are intriguing. More than 5,000 people, aged 55 years or older, and living in nine randomly selected communities in Chongqing, China, took part in the study.

Detailed information was collected regarding leisure activities.
