For over half a century, runners had been trying to break the 4-minute mile. Then, in 1954, Roger Bannister finally ran a mile in 3 minutes and 59.4 seconds. And then, just 46 days after Bannister showed that it could be done, another runner did it.
Since then, over a thousand runners have beat the 4-minute mile. It shows how much of what we think is physically and practically impossible is psychological. What holds us back is often our mindsets.
And that brings us to transportation, climate change, and California bills AB 2237 and AB 2438.
