FACT : your pupils dilate when you see the person you are attracted to.
Because the nervous system controls the muscles of the irises, the response of the nervous system to different stimuli results in involuntary pupil dilation. Another commonly cited reason the pupils dilate is in response to excitement or sexual arousal. When a person sees something or someone he finds very attractive, his eyes may dilate.

Our body is composed of 206 bones that serves as a framework and support for our muscles and soft tissues in the body. It comes to different sizes and shapes but do you wonder what’s the smallest bone in the body?
It’s found inside our ears, or rather, inside the middle ear ossicles that is called STIRRUP BONE or STAPES and is only 0.25 to 0.33 cm long (0.10 to 0.13 in) and weighs only 1.98 to 4.3 mg.
What’s the function of it? It transmits the sound vibrations to the inner ear (particularly the oval window) and amplifies the sound vibration up to twenty times from what they were when they contacted the tympanic membrane/ear drum!
Smallest bones it is but never underestimate the amplifying power of the middle ear!
Tongue? No. Penis? No!
No, you’re wrong! The known strongest muscle in the human body is our HEART.
Yes, it is made of muscle which in medical terms, we call it the MYOCARDIUM or the Cardiac Muscle. Myo means muscle while cardium means heart.
How it became the strongest muscle in the body?
Oh, it only pumps blood and its components, oxygen, and nutrients 24/7 nonstop (unless the body is dead) in every corner of the body. Can your tongue or penis do that?
Amazing, isn’t?
