In today's technology age, most people spend a lot of time sitting at desk looking at a computer, or looking down at their phone. There is nothing wrong with this posture. I'll say it again, THERE IS NOTHING WRONG WITH THIS POSTURE. I wrote this while sitting in that position. However, because of this position and how gravity works, our postural muscles work as our anti-gravity muscles. Without them, we would technically face-plant on our computers and phones ????♂️.
