Stephen Rannazzisi: Slow Pitch Softball

I joined a softball team, which I thought was a great idea... but the guys on my team are crazy. These guys show up to games -- slow pitch softball games -- with cleats, stirrups, the Barry Bonds arm guards on, the black crap under their eyes. Im like, Fellas, the ball is this big. If you cant see it, you probably shouldnt have driven to the game today.

David Shemin

Born 18 Mar 1911; died 26 Nov 1991 at age 80.American biochemist who pioneered the use of radioactive and stable isotopes to trace chemical pathways by which the body creates its own materials, such as blood. He discovered the metabolic pathway by which the cell synthesizes heme (the red substance in haemoglobin), vitamin B-12 and related compounds. In 1946, with David Rittenberg, to investigate the path of glycine in the body, he ingested glycine labelled with atoms of the stable isotope nitrogen-15, and his blood was analyzed for products containing the tracer atoms. Hence they found glycine is used to synthesize the pyrrole rings of protoporphyrin. Further, he found that red blood cells had a lifespan of about 127 days, which led to understanding certain red blood cell diseases. He continued to study the mechanism of the intermediary metabolism of amino acids.«
