The brain of adult men is approximately 10% larger than that of women. Because men are typically taller and have more muscle mass than women, their brains require more neurons to control the body.
Nipples don’t have muscle inside them — the erection of the nipple happens because of tiny smooth muscle fibers in the areola that contract in response to cold, touch, or sexual arousal.
Your gut is sometimes called the “second brain”. The gut has 100–500 million neurons, forming the enteric nervous system that controls digestion independently of the brain.
It takes 2 to 3 hours at 1800°F / 980°C for a body to be reduced to bone fragments? Ash needs even more! (They usually blend the bone fragments in cremations to get ash!)
Even dim light at night can suppress sleep hormones
Exposure to very low levels of light (~30 lux for 1 hour) can significantly suppress melatonin production, making it harder to sleep.
