When lasers aren't choreographed to the music of Pink Floyd, they're busy performing an ever-growing number of tasks. From LASIK corrective eye surgery to assisting symposia keynote speakers point to charts, it seems there's nothing lasers can't do. What other invention of this or any generation can be credited with aiding in the printing of homemade greeting cards, as well as being the primary weapon used to fight the evil forces of Cobra's dreaded Crimson Guard? I don't see Gore-Tex™ making any such claims.
For some time now, I've seen ads for laser hair removal. But yesterday I saw an ad that confused and frightened me. It was for laser hair restoration.
What the...? How can lasers get rid of hair and make it grow?! That goes against everything I know and stand for. It disrupts and kicks sand in the face of all that I hold dear. How does something perform two contradictory tasks? It's like saying keys can open doors, but also lock them. Oh, wait. Well, there goes my whole argument.
It still seems weird though. Maybe different colored lasers do different things. Like, red lasers remove hair and green lasers grow it back. And blue lasers blow up the ocean.
Lasers giveth, lasers taketh away.
