Yeah, bad pun on that title…

Some fun bits (at least if you are as much of a geek as I am) from Divya (I am not sure what her sources are, so no attribution):

• Animals can digest only molecules with one orientation (in an Organic Chemistry sense) though both exist in nature.
• Mitochondria, now part of our cellular makeup, were once free living bacteria. Did you know that they are passed down only the maternal genetic line? (Findings of an underappreciated female biologist: Lynn Margulis)
• Cockroaches can live for 2 weeks without their heads since they have their brains in their legs, but they will eventually die of starvation.
