“Picture yourself in a grocery store with a friend. You both proceed to pick a shopping cart. Your friend chooses a cart that works perfectly fine. You happen to pick one that has a wobbly wheel, that shakes, scrapes and is annoying.
For whatever reason, you both decide to first go to the milk section. At the time you arrive at the milk section, you have both gotten there in the same amount of time, and have covered the same distance.
The difference, though, is that it took you more energy to get there, and it has caused way more stress on your body.”
Here’s how it is relevant.
Picture watching two football players train for the NFL combine. They both are interested in preparing for their 40 yard dash time. Ironically, during their training they are both timed at the exact same 40 yard dash time.
If you knew who ran their 40 with less energy expenditure, and/or who ran their 40 with less stress on their body, YOU WOULD BE ABLE TO KNOW WHO WAS THEORETICALLY MORE EFFICIENT.
It’s about more than how fast did they get there.
It's about what did their body go through to get there.
It’s about biometrics.
