The next time you have an argument with your better half, spare a thought for love on ice couple Chris and Alexa Knierim. The US figure skaters competing at the PyeongChang Winter Olympics are partners on the ice, and married off it. They say you should never take your work home. So, a heated exchange over cornflakes needs to be quickly forgotten if, like Alexa, you have to put your total trust in the man you would have happily throttled a short time earlier. He's the one throwing you up in the air and then catching you - smiling throughout. "Yeah, you can get that kind of situation, with any relationship whether you're married or just work partners," Chris told AFP.
