I got a health checkup and one of the doctors told me...

"You've got a straight back, especially for your height!"

And I was like (internally, not saying out loud) I know, doctor, often times when I catch myself off-guard reflected on a window or something, I get amazed at how upright I am even without effort...

This "omg my posture is so good" feeling is new to me. Definitely one of the most positive changes since I started working out consistently. Thanks FB!
