Randall, some of our answers are opinions, some our answers are answers to some of the questions. We do have a retired dentist, nurses and poeple from all walks of life, but as far as all of us are concerned we are volunteers wanting to answer other peoples questions if we can. We do have a lot of people that we feel come on to AP that would like us to do their homework assignments. If you have read some of our post that we have told people to read their assignments, we are doing this to be mean. We are trying to get people to understand that we are not a homework site, where you can magically write all of your answers to your questions. We do the best we can in answering others peoples questions, sometimes they ask us for advice. We are not experts on every subject, alot of questions go unanswered. When individuals ask for your opinions we try to be honest and give them answer from our own life experiences, Hope this helps
