A friend of mine wrote a column for his university paper while in med school a few years back. i remember following his work via the web while he was at it and enjoyed the articles very much. i happened upon them the other day and thought that you all would find his wit as entertaining as i did. therefore, i will be offering them up from time to time for your amusement and edification. the first selected installment, A Probing Issue deals with the digestive tract, something we all use and also take for granted. carry on and happy digesting.
