I love when I wake up in the morning and everything pops (like when I go to the chiropractor) while I strech! It's all like CRAAAAAAAACK! I know it really isn't super good for my body, but who gives a shit it feels good!

A physiotherapist I know once told me -if I remember it right- that the cracking can simply come from air in the joints and therefore is not bad...

I definitely agree it does feel damn good
