Benefits of singing in a choir studied in San Francisco

Click on that to read the article from the University of California, San Francisco on Medical Press.

    Here's what the study says:

"Overall, the researchers found that older adults who sang in a choir for six months experienced significant improvements in loneliness and interest in life. However, no substantial group differences occurred in the cognitive or physical outcomes or for health care costs."

I think 6 months is too short, and I'm sure that cognitive and physical changes would occur over time as well. What do you think?
