congratulations on your position and i wish ewell. look forward to working with you. one of the things that i will say keeps me up at night because i have various times of going to sleep, what i think about a lot is how this body which moves at its optimum efficiency of about 10 miles per hour can make policy in a world that's moving at 100 miles per hour and this manifests itself in so many areas we deal with in the energy field and education field and medical field where things are changing so rapidly and those obviously all have repercussions for government and the taxpayers and our federal budget. i remember several years ago when secretary, treasury secretary geithner was here and we were discussing these long term projections about deficits and costs of medicare and medicaid and so forth, and i asked him at that time how reliable would you say projections going out 30, 40, 50 years would be. he said i don't think projections past five years are reliable. of course, that doesn't make your job any easier and nor does it make our job any easier. but in your stateme
