Why cockroaches can live without a head

Experiments have shown that cockroaches are capable of surviving without a head for several weeks: their circulation is not controlled by the brain, and breathing occurs through special openings called spiracles, located throughout the body. After losing its head, the basic functions of the nervous system continue to be maintained by ganglia — nerve centers in the body segments that can autonomously coordinate movements and responses. Thanks to this, a cockroach remains alive for some time and can even move, but without its head it loses the ability to feed and drink, so it eventually dies of starvation and dehydration.

Interesting, so cockroaches only need their heads to "eat and drink into them"?

Like many people 🤣

That's exactly what I meant, I just felt too shy to say it out loud, out of respect for the "human race" 😉

One should show respect to one’s kin. As for mindless cockroaches, they live their own lives. 

Therefore, a slipper is a reliable means to kill this abomination

Kills instantly.
