I'm with you on this. I had two surgeries caused by injuries from sitting too long/much. I switched to a sit/stand desk and began doing PT exercises which resulted in a general improvement in my quality of life and resulted in my doctor saying a planned possible third surgery was not going to be necessary. It's like any other lifestyle choice, those choices do have effects. They may not be absolute and they may be different for different people, but if it works for you it works for you. It's silly for people to crap all over us for doing something that we have directly experience an improvement in our lives and work from.
