There is an increase of 85 percent in disc pressure when leaning forward in a poor sitting posture.This means,you are hurting your back while you slouch and lean towards your computer! Imagine the abuse your back has taken through the years?Chiropractors suggest never to sit in the same positions for more than 40 minutes without getting up for a stretch. So,wise up and take care of your spine!
