I can barely walk in the wake of my recent surgery. I have improved speedwise, but I'm still bent over, as slow as an old man, and quickly tired. My sister took me to Target today and recommended I utilize one of the power-chairs.
As useful as it was, I did not enjoy the experience. I'm only in my twenties, so being in a power-chair I imagine I looked extremely out of place. I felt like everybody was looking at me. "What is he doing in a power-chair?" "Does he really need that?" "I wonder what's wrong with him?" I felt so public, and the most humiliating part was the beep-beep noise I made whenever I backed up. I had to go into the wider main aisles to be able to make a U-turn just so I didn't make that noise.
Also, I can't laugh. Laughter hurts - a lot. I keep wandering across hilarious videos on youtube and I can't appreciate them, or have a good laugh. I can't bend down to play with the family dog, or get up out of bed without serious effort. Life avoiding abdominals exertion is hell.

Appendix Is Useful After All, Scientists Say
WASHINGTON (AP) - Some scientists think they have figured out the real job of the troublesome and seemingly useless appendix: It produces and protects good germs for your gut. That's the theory from surgeons and immunologists at Duke University Medical School, published online in a scientific journal this week.
For generations the appendix has been dismissed as superfluous. Doctors figured it had no function, surgeons removed them routinely, and people live fine without them.
And when infected the appendix can turn deadly. It gets inflamed quickly and some people die if it isn't removed in time. Two years ago, 321,000 Americans were hospitalized with appendicitis, according to the Centers for Disease Control and Prevention.
The function of the appendix seems related to the massive amount of bacteria populating the human digestive system, according to the study in the Journal of Theoretical Biology. There are more bacteria than human cells in the typical body. Most of it is good and helps digest food.
But sometimes the flora of bacteria in the intestines die or are purged. Diseases such as cholera or amoebic dysentery would clear the gut of useful bacteria. The appendix's job is to reboot the digestive system in that case.
The appendix "acts as a good safe house for bacteria," said Duke surgery professor Bill Parker, a study co-author. Its location - just below the normal one-way flow of food and germs in the large intestine in a sort of gut cul-de-sac - helps support the theory, he said.
Also, the worm-shaped organ outgrowth acts like a bacteria factory, cultivating the good germs, Parker said.
That use is not needed in a modern industrialized society, Parker said. If a person's gut flora dies, they can usually repopulate it easily with germs they pick up from other people, he said. But before dense populations in modern times and during epidemics of cholera that affected a whole region, it wasn't as easy to grow back that bacteria and the appendix came in handy.
In less developed countries, where the appendix may be still useful, the rate of appendicitis is lower than in the U.S., other studies have shown, Parker said.
He said the appendix may be another case of an overly hygienic society triggering an overreaction by the body's immune system.
Even though the appendix seems to have a function, people should still have them removed when they are inflamed because it could turn deadly, Parker said. About 300 to 400 Americans die of appendicitis each year, according to the CDC.
Five scientists not connected with the research said that the Duke theory makes sense and raises interesting questions.
The idea "seems by far the most likely" explanation for the function of the appendix, said Brandeis University biochemistry professor Douglas Theobald. "It makes evolutionary sense."
The theory led Gary Huffnagle, a University of Michigan internal medicine and microbiology professor, to wonder about the value of another body part that is often yanked: "I'll bet eventually we'll find the same sort of thing with the tonsils."
