I dropped my phone last week and it stopped working. As the daughter, sister, and wife of engineers, I generally regard most broken things as a challenge and I am quite often able to fix them, so I gathered tiny screwdrivers and a good light source and prised the handset open. Inside was a world mostly unknown to me, of miniature circuit boards, teeny candy-striped transistors, and delicate little welds. I identified the problem, but it was beyond repair, so I went out and bought another phone with a renewed respect for the intricacies inside the things we use every day.
