# Usain Bolt can’t outrun a domestic cat
Usain Bolt hit the world record in 2009 with the speed of 44.72 km/h. With that top speed however, he’s still slower than the domestic cat, which can run at 47 km/h. I love this fact as it’s showing how we humans have our biological limitation.

Hitting top speeds, the fastest house cats can run up to 30 mph. That’s approximately 47 km/hr.
Bolt was clocked at 44.72km/h, which is 27.8mph.

- Humans are constrained by biological limits
- Whether we like or not, we are all constrained by our biological limits. We have Working memory limits, we can’t imagine a five-dimensional cube, and our circadian rhythm will tell our sleep pattern. Even Usain Bolt can’t outrun a domestic cat.
- Effective tool circumvents human limits
- Humans are constrained by biological limits, and one way we could circumvent these limits is by the use of tools. Usain Bolt can’t outrun a domestic cat, but you could be faster than a domestic cat by riding a bicycle.
