I was having a conversation about telepathy and blew my own mind. Essentially, telepathy would be a means of sending thoughts to other brains. It would require some sort of transmitter organ to produce waves that travel through space, and then some sort of receiver organ to "hear" the transmissions.

That's when we realized we do have all of that. Our brains convert ideas into words, and we form those words passing expired air across muscles we constrict to form specific wavelengths that can transmit through the air. We also have tiny hairs that pick up the otherwise imperceptible vibration stimulus, and a completely separate area in the brain that decodes antennae hairs back into ideas.

It's so mundane, and yet hardly any other living can manage it, and hundreds of lifeforms have inconceivable forms of communication that we cannot perceive.

Anyway, people rarely marvel at the amazing things we have.
