People know what I'm doing.
I don't need to worry about being idolised.
Age is nothing, can still win the Grand Slam, pretty happy about my age, more experience.
China tennis - we're getting bigger and bigger.
After four knee surgeries and hundreds of shots injected into my knee weekly to alleviate swelling and pain, my body is begging me to stop the pounding.
Tennis is best of three sets, so even if I lose the first set, I still have a chance.
