Who paid these scientists to figure out that: “The top speed humans could reach may come down to how quickly muscles in the body can move. ” Really?? 🙂
My car could also go 300mph if I could get the axle to spin faster and pistons to pump more rapidly.
You can change the gear ratio and size of tires to make it go faster. Which in a sense is either the biggest or second biggest major anatomical problem humans have in not running near the top of the food chain.
