So sitting too much is bad so is that sitting too much straight or total for the day? i take breaks and walk around every 15 or so minutes

Should be ok: If one who sits most of the day is actually getting up and walking around every 15 minutes, that sounds pretty good. The important thing is to be ergonomically correct while sitting. Be sure the chair is a good one, that puts the person into a good back position and proper neck position. The arms and hands need good positioning to avoid carpal tunnel symptoms. The neck shouldn't look down too far.

Taking breaks helps: Prolonged sitting prevents good circulation of blood which brings nutrients to all the cells. If you eat healthy unprocessed foods, take 3 minutes to relax and think of the things you are grateful for, and then take 10 minutes to walk and move around every 3 hours you will end a day of sitting in good shape.
