I’ve had DOGSHIT posture my whole life. Don’t really care about it. Otherwise very fit, active, and healthy.
Now I have a bulging disk and a schmorl hernia in my spine. When that shit starts hurting, it’s genuinely paralyzing. Worse than breaking a bone, and the spine does not heal from that naturally.
I don’t think you have to build a lifestyle around stretching, yoga, proper posture, and mobility exercises, but dear god do some little things to keep your knees, spine, and neck in working order
Never hurts either
