The tongue, lips, and fingertips are the most touch- sensitive parts of the body, the trunk the least. Each fingertip has more than 3,000 touch receptors, many of which respond primarily to pressure.
Some places, such as our fingers and lips, have more touch receptors than other parts of our body, such as our backs. That is one reason why we are more sensitive to touch on our fingers and face than on our backs.
The skin is our body's most sensitive organ. The skin is the largest organ of the body, made up of water, nutrients, lipids, and mineral deposits.
When an area has more sensory neurons there is a larger brain area devoted to receiving their signals, meaning more sensitivity. Most people find that their hands are much more sensitive than their backs or legs. Given how much you use your fingers for, that extra sensitivity makes good sense.
Outer shoulders
The outer part of your shoulders has thick skin with few nerve endings, making it one of the least painful places to get tattooed.
The brain has no nociceptors – the nerves that detect damage or threat of damage to our body and signal this to the spinal cord and brain.
You'll be surprised as to how much you could lose and still live. You can still have a fairly normal life without one of your lungs, a kidney, your spleen, appendix, gall bladder, adenoids, tonsils, plus some of your lymph nodes, the fibula bones from each leg and six of your ribs.
Hormones may play a role in women having more pain sensitivity. In addition, women have greater nerve density (more nerves in a given area of the body)—which may cause women to feel pain more severely than men. In addition, women's psychological experience of pain differs from men's in certain ways.
Our sense of touch is so sensitive that we can feel the difference of just a single layer of molecules, researchers have found. We can easily tell the difference between a range of surfaces, from the roughest of sand paper to a soothing caress.
Differences were especially strong in pain tolerance—even though male participants had higher tolerance, female participants were less variable across visits. According to the researchers, this was the first study to measure gender differences in the test-retest reliability of pain sensitivity in humans.
Women on average report more pain when compared to men, and there seem to be more painful conditions where women exhibit a greater prevalence than where men do. Sex differences in pain vary according to age, with many differences occurring during the reproductive years.
There is a lot more to women's body than just her genitals, butt and breast. You can easily turn her on by touching her other body parts. Some of those hot-spots are the nape of her neck, her mouth and lips, her collar bone and you can always add more to the list.
Reproductive organs aren't vital for survival
Although you won't be able to naturally conceive a child without some key reproductive organs, you can totally live just fine without them. For some people, getting rid of them might be beneficial for other health reasons.
Answer: The eyeball is the only organism which does not grow from birth. It is fully grown when you are born. When you look at a baby's face, so see mostly iris and little white. As the baby grows, you get to see more and more of the eyeball.

Brains can work 24 hours a day with no rest.
In animals, pain studies have had every possible outcome: males have higher tolerance, females do, and there is no gender difference at all. "Human studies more reliably show that men have higher pain thresholds than women, and some show that men have a higher pain tolerance as well," Graham adds.
While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain.
While some studies have reported greater pain severity among women than men,10–13 other studies have found no sex differences in pain severity among treatment-seeking patients. There is a potential for bias in these results as patients with less severe pain are under-represented in these studies.
Men cited women's faces as being their most attractive attribute by 46%. In second place, women's butts came in at 18% followed by hair at 11%. Legs, breasts, eyes, and others composed the remaining 26%.
