Mostly True

The text claims the human body contains 72 km of nerves and enough blood vessels to circle Earth twice.

Infact verdict: Mostly True (60/100).

The claim that the human body contains 72 km of nerves is incorrect based on available evidence. Sources indicate that the human nervous system is extensive, but the specific measurement of 72 km is not supported. The claim that the human body has enough blood vessels to circle Earth twice is supported by multiple sources, which state that the total length of blood vessels is approximately 60,000 miles, enough to circle the Earth twice.

Instead, the length of nerves is often described in terms of their complexity and connectivity rather than a specific distance.
