I believe bone growth is not completely done until about age 24 or so.
According to what I've read the long bones of women stop growing at 18, on average.
I am referring to bone ossification. I believe this would be the same thing as bone density.
See:
http://en.wikipedia.org/wiki/Bone_growthTimetable for human ossificationTime period Bones affected
Third month of embryonic development Ossification in long bones beginning
Fourth month Most primary ossification centers have appeared in the diaphyses of bone.
Birth to 5 years Secondary ossification centers appear in the epiphyses
5 years to 12 years in females, 5 to 14 years in males Ossification is spreading rapidly from the ossifcation centers and various bones are becoming ossified
17 to 20 years Bone of upper limbs and scapulae becoming completely ossified
18 to 23 years Bone of the lower limbs and os coxae become completely ossified
23 to 25 years Bone of the sternum, clavicles, and vertebrae become completely ossified
By 25 years Nearly all bones are completely ossified
Kids should rarely drink soft drinks because sodas pull calcium out of the bones.
I wish I could still grow new bone. For me it's a matter of keeping bone. :geezer:
