I'm 34 years old and found out last year that mine has always been fused, likely since birth as well. Had I not sarted seeing a chiropractor I never would have known. I've been living just fine with it this way. I consider it a super power or maybe those of us like this are just an evolved species or perhaps an anciet species trying to hold on! I plan to do nothing about the fusion as its always been this way and is not causing any issues for me.View Thread
