During these Christmas holidays, I received a greeting card from Professor Marcia Hiriart of Mexico with a message saying "May our growth factors continue to grow in a collaborative effort between our labs." Our in-house evaluation reveals that this should be the thought of Brain-and-Heart Friendship (BHF) for the year 2010. This definitely contrasts to the word of year 2009 "to unfriend" as chosen by the New Oxford American Dictionary, primarily used by Facebook.
