It's remarkable she [Venus Williams] plays at all, given her Sjögren's syndrome [an autoimmune disorder that can cause joint pain]. She's back, winning tournaments. She didn't allow society to tell her, "You have this disease; you can't do that anymore." I look at her, like, "She's not playing at 100 percent. You are. You don't have excuses." Knowing what she went through helped me try to be a more positive person.
Serena WilliamsI'm a high-performance athlete: I'm running, I'm sprinting, I'm sliding, I'm doing pretty much everything and the last thing I want to worry about is my chest. I want to just worry about playing the sport at the highest level that I can.
