I heard someone describing humans as factories of waste!! I thought wow, that man was very depressed and very negative about humans, as he sees nothing other than the digestion process, as if we live to eat.

Evolution via natural selection sculpted our bodies. This is mind blowing to me. Why? Because, even though the body is full of flaws, evolution is a blind bottom-up process, which has produced the most complex known organ in the universe, namely, the brain, which makes you think all these thoughts, and reflect on them. The harmony of the different organs and the healing of injuries and how the immune system works ... etc are something to reflect on.

Other than that, I see the body as a vehicle. It's not a purpose, but a means as we humans have transcended our physical realities by our big and complex brains (in contrast to animals which try just to survive the moment and pass their genes). It helps us to do things larger than us. We are larger than our bodies and its collective parts. The collection of parts is more than the sum of the individual parts. That's why outer beauty loses its value in the absence of inner beauty, because we are no longer after outer beauty as the sole determinant of fitness and power.
