Madam Rebecca Wong, 65, leading the way to encourage her husband, Mr Tay Yam Hwee, 71, at a mass walk yesterday at the Toa Payoh Town Park, during the Parkinson Society Singapore's annual "Move to Beat Parkinson" Day. The event, now in its fourth year, encourages people with Parkinson's disease to be active and to stay positive in spite of their condition. There were about 260 participants, including caregivers, at this year's event, which featured mass exercises such as Zumba and taiji, and games such as decorative knot tying and calligraphy. An instructional exercise DVD which demonstrates exercises that those with Parkinson's can do at home to keep active was also launched yesterday.
