Mare Nostrum IV: Gibraltar–Everyone Wants a Piece of the Rock

…The concept of two pillars, one in the North and another in the South, in those times, would be recognised by all sailors as a religious prohibition, a warning that only the approved might pass between them. The Pillar on the right, sailing out of the Mediterranean towards the Atlantic, Westwards, would be Gibraltar, a grey limestone monolith two miles long and 1380 feet high …The Pillar on the left, on the North African coast would be a lower mountain about 400 feet high, known as Septa… [covered in bushes which] flower yellow in January through to April, presenting the impression of the fiery pillar.
–William Serfaty, The Pillars of the Phoenicians

Mons Calpe. Pillar of Hercules (Ἡράκλειαι Στῆλαι). Jabar Tariq. What the Neanderthals called it is unknown. The Barbary Macaques–The Rock Apes–don’t tell us their name for it either. Nowadays, most humans call it Gibraltar.

Because of an advertising campaign, Gibraltar has long been associated with safety and security. Getting a “piece of the rock” is connected to insurance which yearns for a boring, uneventful existence. However, assumptions which link Gibraltar and peace are flawed at heart. The Rock has reflected 2.6 square miles of arguments and disputed ownership for much of its human history, especially during the last five centuries.

San Francisco, American Phoenix

Today marks the 112th anniversary of the San Francisco earthquake of 1906. Watching the news of the commemoration this morning, I am struck by how the city has throughout its history managed to stand for both old and new. The more I poked around the ashes of the story of this most famous disaster, the more I realized how much it stands for rebuilding and the spirit of renewal.

Perhaps the 50th Largest Earthquake

The 1906 earthquake struck at 5:12 am and lasted for 42 seconds, less than a full minute.  The estimated Richter magnitude is 7.9, which makes it the tenth largest quake recorded in the United States. However, the frequency and size of earthquakes around the Pacific Ocean–from Sumatra to Alaska–means that the SF quake doesn’t even make the list of top forty largest earthquakes in world history.

Earthquakes were not particularly frequent or known occurrences in the fledgling California at the time. The Richter scale wasn’t to be invented for another thirty years and scientists, looking back, don’t think there was a tremendous amount of seismic activity beforehand. But, of course, that is how pressure builds up and the quake is the mechanism that allows the faults relieve themselves when they are crushed too closely together. Pressure must escape and, like a genie released from a bottle, the impact of releasing a giant force from a tiny space is hugely felt. Continue reading “San Francisco, American Phoenix”

Middle-Aged Brains are Smarter Even Though We Tend to Put our Keys in the Refrigerator

Beautiful Brain

Of course my keys are in the laundry basket. Of course my wallet fell out of the pouch I forgot to zip. My middle-aged brain forgets the name I looked up only two minutes ago, how to fix that thing that WordPress always does, and what you just said. Last week, my wife came out of the garage with a piece of paper. “Honey, did you need this list of CDs?” Such relief!  “I was frothing at the mouth looking for that! Where did you find it!” On top of the frozen bagels.

At middle-age, we lose episodic memory. More on that later, if I make myself a note not to forget to write that part. As we age, we do lose cognitive function, and we incur an increased risk of developing Alzheimer’s. But our Over-40 brains also have a lot going for them, as I learned from Barbara Strauch’s fascinating book, The Secret Life of the Grown-Up Brain: The Surprising Talents of the Middle-Aged Mind.

Debunking the Brain Myths: Smarter than a 25-year-old

Believe it or not, we are smarter than we were and, in some ways, demonstrably smarter than a 25-year-old. Strauch cites a number of studies that have had me crowing with pride for the last week. For example, psychologist Sherry Willis of Pennsylvania State University ran a forty-year longitudinal study on the mental prowess of 6,000 participants. This Seattle Study, which covered people of multiple genders, ages, and occupations, found that they performed better on cognitive tests between age forty and sixty than at any other time in their life.
