Beethoven continued to compose music even after becoming completely deaf at age 40 (16 years before his death).
Despite being deaf, he still managed to compose one of his most famous symphonies — "Symphony No. 9," aka The Ninth. It goes without saying that it is pretty damn impressive!
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.
