I'm not sure what this picture tells us, but it said something about 'hearing loss, both ears'. This is what my dedicated husband does almost every Thursday night from 10:00pm to about 2:00am. He scans people's brains, sometimes his own, and tries to figure out what is happening. Okay, it's a little more complicated and specific than that but I don't really know what to say to explain it. I just know that each time he goes he gets one baby step closer to finishing his Masters Thesis. I love my smart husband!
