As much as I like the idea, it does not work in practice. I lived in England. A friend of mine from there thought she broken her leg. We sat in the ER for 12 hours. They x-rayed her and SENT HER HOME....no results, no crutches. They called her two days later to tell her her leg was broken, to come back and they would have to re-break it to set it. That is unacceptable. There has to be a better happy medium. Not this.
