Consider me a member. Friends and coworkers cringe when I habitually crack my back and neck. I tell them that's not the worst, and they should hear my knees when I stand from a squat (or the sounds my bones make when I first wake up). Doctor and therapist said it's nothing to be concerned about, but it even creeps me out sometimes.

What I really mean is self adjusting my back and neck. Maybe it's because of all the decades of self abusing my body in contact and non-contact sports. But I do it during the night - I'll wake up and have to crack my neck back into place, or I'll have to adjust my back into place (discs between vertebrate fill and makes it easy to adjust during the night). I do it before and after a workout. I do it as part of my workout on my roman chair, or on my exercise ball. I do it in the office. I will do it whenever no one is listening as my neck adjustment can be loud. It feels great! And there is no way I can stop, specially at night or in the morning when I absolutely have to put myself back together. I was told that something is released when my vertebrate is adjusted, which is one reason why maybe it feels so good.

I'm a total cracker. And I mean that in every possible way.
