UTMB student Rimma Osipov writes in this guest column: On Saturday, a group of UTMB students invites the Galveston community to join in celebrating Mardi Gras in a very special way by taking part in a Healthy Living Event for adults and children in the Galveston Community. Organized by Students Together for Service, a group that brings together service organizations from across the UTMB campus, this second annual event will take place at McGuire-Dent Recreation Center from 11 a.m. to 3 p.m. The event will feature booths run by students and clinicians ranging from healthy cooking demonstrations to free yoga classes to games and activities for the kids. There will be door prizes for the first 50 attendees, and a healthy living raffle will feature items such as blenders and cookbooks. Some other special activities include a bike safety booth that will provide helmets for children and information booths on fitness, nutrition and sun safety.
