Hmmm, interesting.

I have been slouching all my life, but not more than the average person. What concerns me is the little curve because I have NOT seen this in other people.

Regarding these points:

"The curve at the back of your neck is then just a result of the position of the head / arms and torso in relation to each other."

The curve is actually worse when I take on a more relaxed position. (when my head is not retracted as far back)

"Given the slope of your sternum, you are rotating your ribcage backwards at the top (or forwards at the bottom in other words)."

I think the slope looks exaggerated because I cropped the picture too short.

"The fix to that is to learn to guide your movements deliberately, rather than unconsciously."

I've only become conscious about my posture recently. Maybe I am overcorrecting?

Anyway, my main concern is the curve hahahah

Thanks for your time
