Had a funny comment today.
Someone was complaining that their chair was uncomfortable and it was making their back hurt.
I said I thought the chairs weren't too bad.
And they replied, "Yes, but you have the posture of a god!"
What??
I've had many comments on my posture, actually.
It must look out of the ordinary.
People have called it "perfect".
Didn't know it was God-like though.

I think you mentioned you took on physical labor jobs, so that may be why you have gotten good posture.
