Is it possible for knees to bend the wrong way?

Because that's what feels like mine are about to do. One thing they don't tell you in office school when you join is that it swaddles you from the harsh realities of the physical work-a-day world in weakness wool. Baby soft hands from tap-tapping lightly on a MacBook, wheely chairs so you need not ever stand up, a vertically mechanised box that you hop into to prevent you from having to walk those very taxing ten steps to the next floor. The worst it gets is when you have to pick up the phone (yourself!) and remember the number for the delivery Vietnamese across the road when you are working late.

With those halcyon days a distant memory I'm trying to take the advice of that infamous Aussie Agony Uncle Chopper Reid, but being on your feet up to 12 hours a day, making over 300 drinks, ensuring that 130 people leave full and happy, cleaning up after them and then preparing to do it all again the next day is taking some getting used to. On a rare day off it's all I can do to crawl to the couch where I lie prone with my knees raised in the hope that they will start doing their proper job and bend the right way, rather than doing the feeling like they're going to do the bending the wrong way thing. Then I go back to work, look out the window and see something like this...


So it's not really that bad is it?
