Look, how many times to we have to explain this? Lasers
+ headbands = a very good time. We're not sure what you don't get about that, and frankly we're a little disappointed. Alzheimer's patients like laser headbands (laserbands, for short, artist's rendition above) just fine, since the technology is providing a potential way to scan and diagnose brains for Alzheimer's while the patient is still alive -- doctors currently have to rely on symptoms for diagnosis, and a post-mortem look at the actual brain tissue to know for sure after the fact. There are still a few kinks to work out, but this could be a big breakthrough for the detection and treatment of Alzheimer's, and the fashion ramifications are unimpeachable.
