Roadside Beauty
In the same way that a person can hail a taxi, once upon a time, beauticians were just as readily available. Flag one down for a quick trim, a makeover, or a speedy facial. In the end, just pay the artist and continue the day! Though it violated a lot of modern health codes, this would be a cool career to bring back into fashion.
PET Scans
Forget everything you know about PET scans because while this medical device is still very much in use, it no longer looks as terrifying as it once did. Developed at the Brookhaven National Laboratory in Long Island, New York, this standardized device came wrapped in metal and wires that would make anyone uneasy. Scientists today keep these wires well concealed.
