Oops - not again!

Do we feel sorry for Elise Christie - our short-track speed skater who has a track record (no pun untended) of crashing out or being disqualified?  I'm sure many of you do.  Myself - I think she needs to ask herself whether this is really the result of an unbelievable sequence of bad luck or whether it's something to do with the way she skates - perhaps putting herself in the wrong place at the wrong time, or being too aggressive.  Put simply - is it bad luck or is it me?
