Re: Heavy Schoolbooks.
Do they need all the books that they have in the backpacks?
Sure the playboy and Cosmopolitons can stay but the Tech. books!!!
Ask them what subjects they have and tell them only to put the books for those subjects in.
Also advise them to use both strap supports as carrying more that about 20% of their body weight can give them back problems in later life.
As for putting subjects on ebooks, most sbujects are now in ebook style but some teachers want specific quotes from certain books, besides can all families afford ebook readers?
