If you've ever had a panic attack you wouldn't ridicule it so easily. I have had several of them and believe me, they are no laughing matter.
During a tennis match?
So, if you're nervous, you just get to calla medical timeout? HOw terribly convenient for you.
But, I have a better idea. If you are subject to being nervous or having panic attacks, try something else: Golf, knitting, sewing, gardening. Quite easy to take timeouts for those activities.
But tennis is a sport. A mental and physical challenge. Not up for both, at the same time, playing under pressure, with millions of dollars riding on a single match? (and already amazing enough wealth to support a small country!) Then my heart bleeds for such a miserable excuse for a human being, and make no mistake, that's exactly what Victoria Azarenka is.
