Her bio reads like she's a few decades old, but Haile Thomas in only eleven.

Despite her young age, Haile has been staying busy. She is trying to encourage other children to watch what they eat and make sure they are active as part of a healthy lifestyle.

Among other projects, Haile is the founder of the online Healthy Girls Adventures Club, she's the host of an online show, "Kids Can Cook," and she's also the mastermind behind an event that's being held at the University of Arizona Medical Center on Saturday, April 21st from 11 a.m. to 3 p.m.

It's called the H.E.A.L Festival - Healthy Eating, Active Lifestyle. She says it shouldn't be difficult, boring or time-consuming to adopt more healthful habits.

"You just have to be open to trying new things and getting healthy," she says.

Robert Bailey works in the Pivirotto Health and Wellness Center at UA Medical Center and he says the center was glad to get involved with Haile and her idea, which is part of a service learning project.

The festival will include soccer drills, step aerobics and African dancing.

"It's a wonderful event and it helps promote health, wellness, the whole bit for the entire family," Bailey says.

The H.E.A.L. Festival is being held on the front lawn of the UA Medical Center and in the Diamond Children's Medical Center lobby. The event is free and open to the public.
