Does anybody here feel the need to be in extremely good shape to be a teacher. I am a little over weight and I am working extremely hard this summer to become fit and healthy because I feel that teaching is going to take a huge toll on me. I have one year left of college before I start, but I am preparing. Also, as a guy, do any of you think that having a harsh tough guy appearance will instill some fear in the students? Kinda showing that I'm the "I don't take BS from students so don't bother" type of teacher. I don't know just curious... Also, isn't it a good idea to be in the best shape ever and be a "Role Model" for students? Especially since the USA has a major problem with obesity and weight related problems.
