At the risk of derailing even further, (apologies Joe et al,)

Milk was not "invented" as a rickets deterrent, but supplies many vitamins that a growing body needs, hence the first nutrition we get after leaving the womb.

Gordon Bennett may be a better authority than Willie, but I am sure the illustrious Mr Bennett would agree that a) calcium deficiency is on the up in the under 16s, (source Summary of Directors of Public Health Reports for 2008 - 2009 - DH.) and b) many families who are thinking about diet and health for very good reasons sometimes deprive their children of the require calcium by having unleaded milk. Complications in later life through brittle bone conditions is not linked to socio economic groups, hence the increasing argument for reverting to giving it to younger children. That isn't Willie spouting off, that is the view of the last annual report of The Health Protection Agency. Sadly, they didn't comment on music in the classroom, but paediatric health and welfare is a subject I for one am not in a position to argue with.

That said, I am sure Gordon Bennett knows best. After all, they named a village hall after him in Thurcroft.......
