Yikes! A Queens MacDonald’s and a group of seniors came to an agreement after the restaurant’s management had the police remove the seniors from the premises. Their crime? They were using MacDonald’s as a place to hang out.

Test yourself for cognitive loss  A new online test lets you self-administer a test for early cognitive loss and dementia that can serve as an early warning system or a benchmark. The Self-Administered Gerocognitive Examination, or SAGE, was released last week by researchers at The Ohio State University Wexner Medical Center after tests on older Americans. Of  1047 people who took the  test, 28 percent were identified with cognitive impairment – a figure that held up under more detailed cognitive testing.  The 15-minute test is a simple download; use paper and pencil to fill it in and then share it with your doctor, who can evaluate it with guidance from the SAGE site. Read more by clicking here. Download the test here. Here’s one of several questions on the SAGE test – mathphobes, beware; a couple of the questions might scare you.

What’s new in the cartilage dept? The New York Times’ New Old Age blog interviewed Dr. C. Thomas Vangsness Jr., an orthopedist and the co-author of a new book, “The New Science of Overcoming Arthritis.” The doc answered questions about exercise (nothing pounding – try stationary bike), supplements (het, there’s no evidence, but there’s no harm either), meds (better options are 10 years away) and stem cell treatment (the doc has been experimenting with stem cell injections and the results are promising). Click to read more on the New Old Age.

Brenda, 71 and Keith, 65, finally set a date when Brenda proposed and married recently in 40s garb, signing the register to the song, “Why Do Fools Fall In Love?” Keith told Britain’s Manchester Evening News: “Keith said: “I’ve asked her on numerous occasions, probably three or four times a year over the past 43 years.
