The sutures do get smaller as a person ages but continue to be present and serve a special function of messenger from bone to bone. I have seen slides that show the different tissues from bone to suture and these fibers have special jobs. The cranial bones do not fuse. Period. That is old news and even the AMA acknowledged this about two years ago although the european doctors have acknowledged it for quite some time. Dr. Upledger is not a guru. He is a doc who just pursued an interest and took osteopathic manipulative medicine to a new level. people who take the Upledger institute courses are not his "followers". They are doctors, nurses, pts, ot, lCs and other health professionals who see merit in the modality that he did not originate but has championed. Alison
