Maybe? But perhaps there is a different way to look at it? The human heart will beat 2.5 billion times before it wears out and will cycle the blood inside your body 1000 times per day. It does all this without ANY shut down for maintenance and it does so with ZERO input from us. The human eye can autofocus to both low and high light conditions better than almost any modern camera. The human fingertips can grip objects effectively above and below water. The human nose can recognize millions of smells and the brain can ascertain information as a result of individual smells. The human body is self-healing, if it is cut the body will purge the cut with blood, fighting off infection, and then seal itself and self-heal! Regarding fuel, the human body can be powered on almost an uncountable amount of different fuels depending on what is available in the natural habitat. The human mind can comprehend and recognize patterns that allows them to create beautiful and complex music. The sweating system allows humans to cool their bodies in a way to a level of effectiveness that no other mammalian life form on earth can come close to competing with and as a result humans can farther without resting than any other life form. I didn't even need to consult the internet to come up with that handful of things above. And I'm sure most anyone (yourself included) could come up with many, many more. Even small things like our eyebrows and eyelashes keep the water out of our eyes, and how we can obtain Vitamin D simply by standing in the sunlight. The list you linked has things like "Knees can go out... Can't easily absorb vitamin C... Women get UTI's if they are not careful". Do you really think that list from Gizmodo justifies overlooking the amazing aspects of the human body? Do you really feel that if the body was designed it was designed by an "idiot"? Don't you think that perhaps you might be overlooking all the amazing elements and hyper-hyper-hyper-focusing on a handful of "less desirable" elements?
