Ketchup was originally sold as a medicine in the 19th century.
In the 1830s, ketchup was sold as a medicine that could cure indigestion, diarrhea, and even jaundice. While the medicinal claims were later debunked, the condiment caught on. Man, I wish I lived in a time when a bunch of ketchup on fries was considered health food!
If we used hovercraft instead of wheeled vehicles, we would not have to waste tens of billions every year building and maintaining roads; we would just need a few guardrails here and there to protect landscaping. And no need for spreading salt and brine to melt road ice because the hovercraft would basically treat all surfaces the same, whether lawn or snow or water it would make little difference.
Also, damage from accidents would be negligible, so insurance rates would be minimal.
Not to mention that squashed critters due to tires running over them would be a thing of the past.
So it seems like the Aztecs were ahead of their time.
