How Did We Survive Without It?

Watched a guy doing a lecture a few days ago. He kept putting a red dot on the screen with a laser pointer as he talked. It occured to me that we live in wonderful times. Used to be that people had to just point at stuff with their fingers. Some of you remember those primitive times. Now, thanks to technology, we can put a red dot on exactly the spot we're wanting someone to look. And that's just the beginning of what you can do with a laser pointer. I saw a guy take his laser pointer apart and reassemble it so the beam was hot enough to actually light a match! What a time saver that must be! Being able to light matches without dragging them across the back of a matchbook probably frees up hours in this dude's schedule.
