Dear Heather, neat site!  Article is 1998 Nov. Lucas et al in BMJ.  Next
question: I downloaded full text (took 2 min).  Where did it go in  my
computer?  How can I print it out?  Oh I am so pathetic.  But this would be
so much easier than trudging to the library!  Oh you mighty computer
experts, please enlighten me (in easy to understand steps, please).
Sincerely, Pat in SNJ
