Located in Center City Philadelphia, the Mütter Museum’s initial purpose was to educate future doctors about anatomy and medical oddities. Now open to the public, its mission has expanded to “tell important stories on what it is to be human”. The exhibits, however, could suggest otherwise: 2000 Objects Collected from People’s Throats, The Soap Lady (who inexplicably mummified to adipocere), skeletons of Siamese-twin infants, among dozens of others. The exhibits are frequented, one could argue, not because they reflect daily experience, but because they exist so beyond what is perceived to be common and palatable.
In high school, I believed the museum was an endless freak show and on occasion would take dates there to elicit their gut-churning. Raised in a Catholic, working-class neighborhood, I was taught that the incurably deformed, the terminally ill, and death itself were never to be pondered or discussed, but feared and eventually mourned. A mysterious black cloud hung over a human’s final moments, where the will to survive was undone by one’s own finite timeline.
In short, a visit to the Mütter was an implied act of rebellion. And how surprised I was, each time, when my dates and I wandered not with nausea, but a shared, unspoken curiosity. Two decades later, my daughter came into the world with meconium jammed in her lungs. If Daisy were born just a century earlier—a blip in human history—I would not be a father. How many teens today know a newborn can die because her tar-like shit went down her throat? And the adults—now that we know that these same lungs can be cleared within minutes—are we any less loving when we lower our heads and kiss the infant squarely, as if we were the ones who needed the blessing?
Dr. Fucking PA, indeed! I think it’s time I switched careers and became a Funeral Director! At least then I could handle things all in one go! Quite simple! Just toss my sorry, sad sack, ass right into the incinerator and that would be it!
I don’t know if I want to rip out my hair, cry or both! Probably the latter, even more, and then incinerate myself!
Today was my first day of school, but last “night” might have been it, in reality. Not knowing what the hell I was walking into, I ran through the chapter in the textbook they would be covering. Oh.My.God. Where do I begin? *crosses eyes*
How does being at it for at least five hours minimum, sound? Maybe six hours? I finally started to get ready for bed around midnight.
I am late to the class. It has already been “clipping along,” however, I didn’t realize just how much. They have their final exam in a month!!! I want all of you to imagine what my face looks like right now. I took a Valium/Diazepam on the way home today after we were done. I didn’t even know how I felt at the time. Nonetheless, I thought it a good “pre-emptive strike,” as I sure didn’t have a clue how I’d feel in the next five minutes!
The course is comprised of mostly terminology, and not so much Anatomy and Physiology. This came as quite a surprise. In fact, it’s much more than mostly terminology. And some of these terms?! I mean, now it’s time for me to eat an entire bakery of Humble Pies! Dr. PA is pretty good but…
Not to mention, this is lots of fun for her loss of ability to spell and retain verbal information, due to her loooovvvveeeellllyyy Anticonvulsants. It’s not that I don’t love you, my pretties; you keep my bean in fairly stable shape. In a lot of ways. For all the goddamn things that are wrong with me!!! Still, you’ve made me stoopid and loopy in my bean (despite all the goddamn things that are wrong with me!!!)
This is also a real gas for my Dysgraphia!!! Oh, Bloody Hell to the nth degree! Attending school is bad enough, but when you’re dealing with some words that are 15 characters in length? *bangs head on desk* Even if I do know the term, I can still screw it all “around the world” in 80 days minutes seconds no, days…because it TAKES me that long to fix it!!!
I took the Instructor aside during a break to ‘fess up about the Dysgraphia and the Asperger’s. She said it was fine, everything would be taken slow. Pfft. Cold comfort, if you ask me. I’m not complaining, though. Both she, and all of the other students, are great and very helpful.
At least I got my assignment done, and only one wrong mark. However, more lovely testing on the above chapter, tomorrow. That means I need to do some more review tonight. I was so overwhelmed by simply doing the work, plus figuring out how the class was run, trying to understand the course’s overall structure…
The Instructor is going to prepare me a little “package” for the previous eight chapters. I do want all of the information–I need it! Between learning all of the material as we continue to move on, I also have to get that previous stuff sorted in a cohesive manner. I need to bring all of the elements together. None of it will make sense if I don’t. I know how to do it; or how I want to do it. We all learn differently, and I know “my style.” I know what is effective for me. It’s just going to take me so long!
Well, as a true “medical student,” I guess I’ll be working non-stop, all the hours I can, and then try to fit in what’s left for sleep and food! *rolls eyes* Then I’ll move on to my next course, or “rotation.”
Just to leave you with my favourite term from Chapter Nine, here you are. Also, I’m not giving you a definition. Think how well this one went over with my insane Dysgraphia!

If you haven’t noticed, the popularity of hand sanitizer has exploded. We are obviously obsessed with killing germs and fighting viruses. It’s in our desks, cars, purses and homes. I have seen dispensers at subway stops, hospitals, airports and restaurants.
With H1N1, Mad Cow, SARS and others, you can’t blame us for being careful. It seems like hand sanitizer came out of no where, but it’s not new, and neither is the principle.
The first time I saw hand sanitizer was in 1995. I worked at a restaurant and we were told to use it hourly. At the time, it seemed like a magical potion. I thought the concept was weird: I wasn’t washing anything off my hands, I was rubbing it in.
The truth is, hand sanitizer is more effective at killing bacteria than soap and water. That said, soap and water is far more effective at removing visible dirt.
For the most part, hand sanitizers use a variety of alcohols as their active ingredient. To be effective at reducing bacteria, they should contain at least 60% alcohol, and most contain 60% to 85%. A few brands (worth avoiding) contain as little as 40% alcohol and some hospital solutions have as much as 95%.
So, where did this idea start?
It began in 1867 with a British surgeon, Joseph Lister. He published a series of articles in the British Medical Journal stating that surgery patients had less tissue infection if the incisions and surgical instruments were treated with carbolic acid prior to surgery.
At the time, they didn’t wash their hands or anything else before surgery. They thought gangrene wounds were caused by stinky air. Seriously. The same stinky air they blamed for cholera, black death and bubonic plague. They later realized the stinky air was actually the result of rotting wounds, not the cause of them.
His work lead to the germ theory of disease. It was the equivalent of suggesting the Earth was round, when everyone else thought it was flat. Fortunately, it was very easy to demonstrate the success of his theory and it became widely accepted.
In 1879, Listerine was named after him. It was originally developed as a surgical antiseptic, but that’s a pretty small market. So, they began marketing it as a floor cleaner and a cure for gonorrhea to increase sales. That brought the company revenue to about $115k, but marketers had another idea in the 1920s.
In this era of patent medicines, there were products to cure every known illness. The Listerine folks weren’t going to let this bandwagon pass by. All they needed was the perfect illness, something that everyone had and Listerine could cure. They made up the term, “chronic halitosis” (bad breath).
You see, bad breath hadn’t been invented yet. At that time, bad breath was just known as “breath.” Their best effort was an ad campaign that suggested young people would never find marriage with a condition such as bad breath. Over 7 years, revenues skyrocketed to $8 million.
Listerine is still sold as an antiseptic today, and primarily marketed for oral health. Depending on the flavor, it contains 21.6% to 26.9% alcohol.

I must be every round the world trip advisor’s dream. I came in saying I wanted to go anywhere but here with money not being an object and left with a ticket for 15 destinations in 12 countries. I finally felt a little bit like myself again. Round the world travel is my new religion and Lennert is my new god.
Maybe it is my age, maybe it is character but I have a general feeling that my life needs a new direction. Yesterday I had lunch with a friend from medical school that I had not seen for four years. I was not very surprised to see that four years had not done much for him. Still his usual self and still very proud of his extremely decent and riskfree life.
I am just incredibly fed up with all these people so proud of their well-paid jobs and their expensive houses, getting married, having children, going on package holidays six weeks a year. If that would be my life you might as well put me in a straight-jacket and hurry me off to the loony bin.
Point is that you only live once and life is not a sum of what happens to you but rather what you make of it. People die, relationships break up, jobs do not turn out as expected – so what!
