== Reference 68 needs more information == 

 Reference 68 on the importance of height in male attractiveness is not complete enough.  The reference reads: 

 Pierce, C.A. 1996; Cunningham, M.R. 1990; Pawlowski B, Dunbar RI, Lipowicz A 2000. 

 I do not find any previous references in the list with these author names.  Thus I believe we need the rest of the publication information for these three sources.  Can the person who provided this reference fill in the data?
