We’re really worried about this because there’s sort of this critical time between being born and reaching the early 20s when you’re setting up the scaffolding of life (in terms of the geometry and density of the bone), you sort of max out in your early 20s and there is real concern that the lifestyle of young people nowadays versus 40 or 50 years ago is setting people up to be more at risk as adults for not having a very robust bone bank as they age.
