Edgar De Leon, Centreville "I have Parkinson’s Disease. Basically, I keep working full-time. I’m a building engineer, so it’s very physical. I go up and down, rarely use elevators. I use the stairs. "I commute from Centreville to work downtown every day, and I walk six blocks from the Metro station to my office. I do a lot of walking. "I try to eat sensible meals, I like fruits. I eat a lot of fruit, five or six servings a day. Banana, apples, strawberries, grapes. I drink a lot of water, too."
