I had so much fun with the Official May Blogathon Guest Post Day last Thursday that Webb of Science is doing another Guest Post Day today. This week I’m hosting Jennifer L.W. Fink of Blogging ‘Bout Boys. One of the treats of this month long blogaganza has been making new friends and reading their work. I’ve enjoyed reading Jenny, and I hope you’ll enjoy her guest post.

By the way, if you’re looking for me today, I’m visiting Jenny’s blog with a Molecule-of-the-Weekesque post about testosterone.
