Today, we would like to talk about the differences between men and women. You might say that you’ve known about these differences for your entire life, but it’s not that simple. We are sure that we’ll be able to highlight a few facts you’ve never heard of before. And in the bonus section, you’ll find out where the fashion for high heels came from.
The length of fingers
Let’s conduct a short experiment. Place your hand on a flat surface and compare the length of your index and ring fingers. In general, in women, the index finger is longer. In men, the ring finger is longer. How can this be explained?
According to scientists, the length of these fingers depends on the level of male and female hormones that affect the fetus in the womb. So, the reason why the ring finger is longer than the index finger in men is testosterone.
The skin on the heels
Scientists have found out that women’s skin is more hydrated in the décolleté area and on the hands. Only the skin on their heels is dryer than that of men. So, in equal conditions, men’s heels will be smoother.
Breast
You might think, “Why would a man need nipples?” It might sound strange but every person was initially female. When an embryo begins to develop in the womb, the male Y chromosome doesn’t immediately start working.
During the first 5-6 weeks, development occurs only under the influence of the X chromosome, so the nipples have enough time to form. If the embryo is male, the Y chromosome “turns on” after this period of time, and a boy is formed.
Men can even produce milk. Lactation is activated under special conditions, for example, it may appear during treatment with the hormone prolactin.
Vision
Women are better at seeing colors, but men are good at tracking fast-moving objects. This is probably linked to our hunter-gatherer past when men were hunters and women were gatherers.
For example, an orange may appear redder to a man than to a woman. The grass is almost always greener for women because green objects appear more yellow to men.
Gaining muscle mass
Many women have to go to the gym regularly to have a toned body, while a man can just lift a barbell a couple of times to get a 6 pack. So, what is the “ingredient” responsible for muscle development? If you guessed testosterone, you’re right.
In women, it is also produced, but in much smaller quantities. So, it is easier and faster for men to gain muscle mass.
Hair loss
Going bald after the age of 50 is typical for around half of men (and for a quarter of women too). The reason for this is a widespread hereditary disease, androgenetic alopecia, which is also called “male pattern baldness.” Due to this condition, hair follicles shrink, and hair becomes thinner and shorter, and eventually disappears.
Follicle shrinkage can be caused by sensitivity to dihydrotestosterone, a by-product of testosterone. This means that the more muscle-building hormone a man has, the more likely it is that he will become bald.
Adam’s apple
Both men and women have an Adam’s apple, but it’s more prominent in men. Why? The Adam’s apple is the cartilage that protects our vocal cords. It is formed during puberty. Since adult men have larger vocal cords, their Adam’s apple is also more prominent.
By the way, the larger the Adam’s apple, the deeper the voice. There is a theory that our ancestors needed a low voice in order to scare away predators.
Brain size
A man’s brain is larger than that of a woman, but this doesn’t mean that men are intellectually superior to women. Also, some parts of the brain in both sexes are different in size and work differently. For example, the hippocampus, which is involved in learning and creating memories, is larger in women. And the amygdala, which is associated with experiencing emotions and remembering them, is larger in men.
Scientists conducted an experiment: they showed the subjects a video so that they could recall some personal experiences. It turned out that in men, activity was observed only in the right amygdala, and in women, only in the left one.
Beard
At first glance, it might seem that a beard doesn’t provide any benefits. So, why does it grow? There is a theory that the jawline looks more massive thanks to a beard, so its wearer looks stronger and more masculine. Perhaps, our female ancestors tended to choose men with a thick beard as their partners because they thought they would produce healthy offspring with them.
Bonus: Heels
Nowadays, high heels are one of the symbols of femininity, aren’t they? However, in the 17th century, Persian riders used to wear one-inch heels. And since owning horses was a symbol of wealth, heeled shoes also came to signify money and power. The Persians then brought their fashion to Europe.
The French king Louis XIV became a big fan of heels. He even issued a decree according to which only nobles were allowed to wear heels. The higher and redder the heel was, the more powerful the wearer was.
The Sun King only allowed those who he favored the most to wear red heels. But since the 18th century, heels have become a purely feminine attribute, although this didn’t stop rock stars like David Bowie and The Beatles from wearing them.

9 things you should never plug into a power strip
When we think of the past, one of the first thoughts that runs through our mind is how people lived without electricity. Nowadays, we can’t even imagine a day without it because all of our appliances and devices run on electricity.
The truth is, however, that most homes don’t have enough power outlets to keep everything running and charged, so most of us rely on power strips without being aware that appliances that consume a lot of energy become dangerous fire hazards when we plug them into a power strip.
Although power strips are the thing to go to when it comes to charging your phone or power an entertainment setup, there are certain devices that should never be plugged into a power strip.
Air conditioners, space heaters, toasters, and other appliances that use high wattage can easily cause power strips to overheat, which can easily lead to a fire hazard.
Even before plugging anything into a power strip consider the ammount of power they support. This is usually listed on the product itself.
High-capacity appliances need to draw a lot of power through an electrical circuit to work. Keep in mind that an appliance does not need to be large in size to draw large amounts of power.
Below is the list of appliances that should never be plugged into a power strip.
1. The oven: Even though the oven is not used continually, it is a power-hungry appliance that should not be plugged into a power strip. In fact, it should be plugged into its own wall outlet on its own circuit.
2. Refrigerator: Refrigerators require a lot of power and frequently cycle on and off which can easily overload a power strip and cause damage. Much like the oven, refrigerators require a wall outlet dedicated solely to powering the appliance.
3. Washing Machine: When turned on, washing machines pull a lot of power. This is the main reason why these appliances shouldn’t share a receptacle with any other appliance or device.
Most washing machines use a max of up to 1400 watts, putting it dangerously close to the max load of most power strips. On top of that while working, washing machines are usually left unattended and work longer hours, at least an hour, which is long enough for a power strip to overheat.
4. Heating: Portable heaters should never be plugged into a power strip because most of them use 1,500 watts of energy on their high setting and they usually run for extended periods of time.
5. Microwave: Since they consume a lot of energy when used, most microwave ovens are plugged into their own receptacle and that is always a good practice.
6. Coffee Maker: Those who own a coffee maker are not fully aware of the power these appliances use, and this is why they should never be plugged into any sort of power strip or extension cord.
7. Toaster: You may think that browning up slices of bread or bagels doesn’t require a lot of energy, but the truth is that toasters use a lot of energy when in use and they should be plugged directly into the receptacle rather than a power strip.
8. Another Power Strip: Power strips are not meant to be used in conjunction with another power strip, although many people do exactly that. This, however, violates most safety codes because it can easily lead to overloading the electrical system.
9. Electronics (Computer, TV, Router): These types of electronic devices don’t necessarily use a lot of power on their own, but they are sensitive to surges and you can find yourself with a burnt out computer or TV very quickly if you plug them into a power strip.
If you want to protect these sensitive devices from power surges, opt for a power strip that functions as a surge protector.
