Does anyone else's chest crack in the center? I've experienced it as long as I can remember so ive always assumed its normal and it happens mostly when I've been laying/leaning on my side then get up. Doesn't hurt, if anything it's an ackward misaligned feeling pressure and I pop it by either pushing my chest out and shoulders back or spreading my pecks apart by hand. I know it prolly gonna come back at me as a dumb question like,"why do my knuckles crack?", but I'm just curious if its common or not.
