Feel like a nice cool glass of ice water? Before you take a sip, you might want to take a quick tour of your home. How’s the fill valve in your toilet? Do you have a vacuum breaker on your outside spigots? What about your boiler?
Think back to an important event in your life: a graduation, a birth, a special Thanksgiving dinner. Chances are you're remembering not only what happened, but also where it happened. And now scientists think they know why.
As we form so-called episodic memories, the brain appears to be using special cells in the hippocampus to "geotag" each event, researchers report in Science. The process is similar to what some digital cameras do when they tag each picture with information about where the image was taken.
On Thanksgiving morning I'll be making pies with my mom, just as I have ever since I was a girl. But at some point I know we'll be talking about more than shortening versus butter. We'll be talking about how she would like to die.
A few months ago my mom fell at home and ended up being admitted to the ICU with four broken ribs and internal injuries. She was lucky. After two weeks in the hospital and a few more in a rehab unit, she's back home, using her new blue walker to get around.
