To answer this question, I am going to employ two metaphors:<\/p>\n
<\/p>\n
As children many of us pedaled about on a bicycle equipped with training wheels. Were it not for the training wheels, we would have taken\u00a0an unfortunate spill. That day would finally come when, after our legs had become stronger and our core able to balance comfortably, our parents would undo the training wheels and\u2014whoosh!\u2014we\u2019d be off down the road. The training wheels provided us with the necessary practice to ride a bicycle.<\/p>\n
<\/p>\n
As children many of us have seriously injured our legs, be it a twisted ankle or a broken femur. Afterwards, we had\u00a0to move about on crutches as our legs healed. Crutches are necessary to help an\u00a0injury heal. Once the cast is off, however, our legs are withered, and an act as simple as walking to the fridge for some milk becomes very difficult. Indeed, we are tempted to use the crutches, as our ability to move with them is far more efficient than to hobble about on our atrophied limb. Ultimately, though, we must ditch the crutches in order to recover our ability to walk normally. Otherwise, though we may be consummate crutch users, we\u2019ll always move in a compromised fashion.<\/p>\n
