'I gave everything to boxing and still have nothing'

Heather Hardy, with her left eye completely swollen and blood streaming from her forehead, insists to the ringside doctor that she wishes to keep fighting.

She confidently returns to the center of the ring, pounds her chest, and exclaims, "I don't care, I don't care."

The nearly 20,000 fans at the American Airlines Center in Texas stand up, erupting in a massive cheer, honoring her as a true warrior.
