"I'm still trying to understand why anybody would consider this article relevant."

Relevant to what? This is Around the Campfire, so can't we talk about anything? We could talk about the color preferences of mice ( http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6W9W-49SFF11-2&_user=10&_coverDate=12%2F31%2F2003&_rdoc=1&_fmt=&_orig=search&_sort=d&view=c&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=bb1d58c83b7a76ed709579ecd5bc943d ) or recipes for cooking your own dog food. We COULD even talk about zombies and pirates!
