five years??

["Hamaker, Charles" <cahamake@email.uncc.edu>]

In an obituary in this weekend's New York magazine the author 
says among other things:

" some science journals now prohibit authors from citing papers 
more than five years old. "

Does anyone one have any evidence of this as a policy for any
journals-if so can you tell me which journals?

Thanks
