You know you are...

...becoming overly competitive when:

• you have an urge to scream 'Losers!' when your bus overtakes another;
• you speed walk home so that 'the bitch' that got a break in traffic and thereby a significant headstart doesn't beat you;
• you swim an extra five minutes so you don't look bad compared to the seventy-year old grandmother that has been outpacing you for the last hour.
