Why are Tattoos Permanent?


Human skin has 3 layers namely Epidermis, Dermis, and Hypodermis(top to bottom). Each layer is made of completely different types of tissues, which is the main specialty of our skin. The Epidermis is made up of Epithelial Tissue which is an average of 50 cell layers thick and usually every week some new layers get added below and due to lack of blood reachability, the upper layers fade away or say die. The Dermis layer which is the second layer is made up of Dense Irregular Connective Tissue. This is basically the layer where the ink is deposited and lasts for years. This layer has got Fibrocytes(cells) which produce protein fiber called Collagen. Also, this layer has all other stuff like nerve endings, blood vessels, hair follicles, etc.

Now when a foreign substance(ink) enters this layer, a process of inflammation starts due to which white blood cells get to the site of ink. Usually, white blood cells digest or break down the foreign substance that comes in like viruses, bacteria, etc. But here we got ink that cannot be digested or break down. And this leads to a process where these white blood cells collect that ink and isolates it by keeping them there and not letting them go all over the body. And we can see that ink over the surface of the skin, and when that white blood cell dies, a similar process occurs and new white blood cells collect the ink again. Talking about the Hypodermis layer, it is made of Fatty tissue, which by name we can say that it helps to create a blur or say shade effects in the tattoo, as we know that ink spreads in fats or oils.


PRO TIP: As the thickness of the Dermis layer is different at each part of the body, making a tattoo from a professional tattoo artist is recommended. As he/she knows how much pressure should be given on the needle according to the place of the tattoo.

#VIKAS_GAYAB_HAI

#VIKAS_GAYAB_HAI , One of the trending topics on Twitter, gaining a lot of attention due to the realization of truth to many people. Well the duty of people is not actually comparing the drawbacks of the previous government with the new one, but people should actually question the progress and what actually, the new government is doing for the betterment of the country. Before a party comes into the ruling, it publically declares policies and aims that they would focus on and improve in their ruling period which we call it as Manifesto. So not actually considering the latest manifesto of 2019 we just jump at the start that is the promises Shri Narendra Modi gave in 2014 manifesto. Their main goal was 'Ek Bharat, Shrestha Bharat'   with the path 'Sabka Saath, Sabka Vikas' . Well, saying words is easy but implementing them is always hard so not talking about all the promises let’s just focus on a few main promises.   Price Rise Promise: Special courts to stop ho...

Attention! Is it needed?

What do we all need to survive? Air, Food, Water, Shelter! Yea this looks good, maybe you would add love, family, or friends but among all these needs attention is also like a basic need in one’s life. We are most of the time unaware of it and some try to pretend that they don’t need it and that’s a good tactic nowadays to attract people in Social Media. Attention is a concept of Cognitive Psychology , the science of what you think, or what people think. It is not just focusing on the specific stimulus but sometimes it’s like fulfilling your needs of attention even you not knowing about it. During childhood days when you are unable to speak and need something, you start crying to get attention from your parents, and slowly when you learn something new you try to go to your mom dad and share it with them cause you like the appreciation, attention, and love they give you in return. People think and create an image that the child is so good, cute, and loving by seeing this behavior.  ...

Comeback

The two biggest weaknesses and strengths humans got are, first is we trust people too quickly, and second is we judge people too quickly. Now you may call these two your strength or weakness. People usually advise us that life is always hard, we lose some people and we gain too, focus on positivity, etc. But for me, life is just present. No past, no future, no thoughts, nothing. Comeback in life is nothing but giving yourself some time. Time, that may heal your past, but importantly it may make you realize your mistakes. I will never say it's going to be easy, it never is. But remember it's not just you who have gone through all this. Ignorance is never the key. Ignoring your past, or karma doesn't lead you anywhere. Today you may ignore it, but one day it's sure you have to face it. So instead of running away just try to face it. What people need the most in their life is "Love", a word worth millions of feelings and emotions. What people need is someone to h...
