Then watched her sister, Venus, win, and later on she and sister Venus won the doubles, making it their fifth Wimbledon win. That's sister love. ''I was definitely inspired by Serena's singles performance,'' Venus said. ''Obviously it's wonderful to play on the court with her. I couldn't have done it without her, so it's great.'' The wins are even more spectacular considering that both sisters have overcome serious health issues over the past two years: Venus having been diagnosed with an energy-sapping illness and Serena overcoming blood clots in her lungs and two operations after cutting her feet on glass in 2010. ''She's such a fighter, you never say die,'' Venus said about her sister. ''I don't think either of us believe that we can be defeated by anything. Nothing has defeated us yet, so we're going to keep that track record.''
