Ken I don't have bad posture and also don't slump but I have depression or are you saying that mine is not real?

There are a multitude of reasons for depression and sometimes none that can be found but to expect people to just believe your theory without backing it up can be harmful to others. You also seem to think that your theory is the only reason, have you ever thought looking at a previous post you have that the reason may be down to some of the things that you have been through ?
