Sorry, but you're wrong. The human body is not a machine. The human body is a collection of chemical processes. Chemical processes must obey the laws of thermodynamics. Among those is the second law, which dictates the tendency toward disorder. We, as humans, are allowed to "disobey" the second law because we represent far-from-equilibrium forms known as dissipative structures (http://en.wikipedia.org/wiki/Dissipative_structures http://en.wikipedia.org/wiki/Dissipative_structures). Now, you might say that any machine is a collection of chemical and physical processes. Fine. If you want to perpetuate a machine analogy, consider this: the camshaft in your car is subject to chemical wear through oxidation, etc. Eventually, the gear teeth will wear out, and it will need to be replaced wholesale. Fine, you say, we'll make replacement parts. But what about the brain? You can replace any arbitrarily large set of components in a car's engine and still call it the same engine, but do you think that holds true for humans as well? And even, say, we figure out how to preserve the human brain (or even, gasp upload it)...problem solved, right? Nope, sorry again. "You" are not your brain. "You" are an emergent property of your entire body. Your brain without your body is as much "you" as your body without your brain is... Bottom line: study some biology. It's not as simple as the "easy A" course you took in high school or college led you to believe.
