As part of a nation-wide tour, on March 8, Rainbow Light’s Mobile Bone IQ Center will give free bone density screening (a $500 value) and education about the importance of bone loss prevention. The noninvasive test takes one minute and provides a printout of bone density results and comparative results with age and gender groups that can be shared with a personal physician. The scanner measures bone mass with real-time ultrasound imaging of the heel bone. March 8, from 12pm to 6pm at New Leaf Community Markets, 150 San Mateo Rd, Half Moon Bay. http://www.newleaf.com
