If we do in fact only use 10% of our brain, what would happen if we could use the other 90%?
If I was able to use 100% of my brain, a lot of things would be different. I would definitely invent a lot of new technology to advance our society. I would invent portals and a time machine. I would develop new and easier ways of communication and more efficient ways to run our society so there isn’t such a high percent of people who are struggling and/or living in poverty.
Then I’d invent a feather weight jet pack, a vitamin that replaces sleep, and find a way to breed animals to make a unicorn.
