Also note that incandescent bulbs are glass and tungsten, as are CFLs plus some phosphorus and a speck of mercury. Both are pretty simple to make. LEDs are made of indium, gallium, arsenic, zinc, selenium, phosphorus; and require a wafer fab factory ($$$$$$$$$$) to make. In China.
Speaking of those hot air dryers - ever tried to dry your face with one? In Florida?? In the summer time??? Doesn't work. Your face will get wetter, not drier
