Why Tattoos Remain in the Skin Permanently and Do Not Disappear Naturally?

Tattoos remain in the skin permanently due to the way the ink is deposited and how the body's immune system responds. Here are the key factors: 
1. Ink Placement: Tattoo ink is injected into the dermis, the layer of skin below the epidermis. The dermis is more stable than the epidermis, which sheds and regenerates regularly.
2. Immune Response: When the ink is injected, the body's immune system recognizes it as a foreign substance. White blood cells called macrophages attempt to engulf and remove the ink particles. However, the ink particles are too large to be completely broken down and removed.
3. Macrophage Cycle: Some macrophages that ingest ink particles remain in place in the dermis, keeping the ink where it was injected. Over time, other macrophages may also ingest the ink particles, but they also stay in the dermis, maintaining the visibility of the tattoo. These cells before dying give birth to new cells by cell division and transfer the ink to the new born cells genetically. 
4. Ink Stability: Tattoo inks are designed to be stable and resistant to breaking down over time. This contributes to the longevity of tattoos in the skin.

Together, these factors ensure that tattoos remain in the skin and do not disappear naturally.

The Oval Office Mango Mandate

  Disclaimer: The following narrative is a fictionalized and exaggerated portrayal of a hypothetical event, written in a satirical style. It does not represent actual events or statements made by Ronald Rump. (The lights hit the stage, a familiar figure strides out to thunderous applause and a roar of  patriotic slogans. He adjusts his tie, takes a sip of water, and leans into the microphone, a mischievous glint in his eye.)  "Folks, folks, let me tell you, it's great to be here. Just tremendous. We're doing things, big things, for this country. Nobody’s ever done what we’ve done. And you know, sometimes, even the little things, they become… battles. Tremendous battles. Even for your, frankly, very stable genius president. You wouldn't believe what I had to go through just last week. You all know I love our country, I love our people, and I love, frankly, the best of everything. The best. So, I thought, you know what? We need some mangoes. Not just any mangoes, the be...

The Fever of Being Viral

Image
By Arshad Usmani All of us live with our past. All of us allow it to shape our future. But some of us know how to shrug the past. I think that is who I am...  Although I was not like this always until one day which changed my whole life. That was the day when I decided to die and even my parents would have totally supported it.They are that good and believed in me. And that actually keeps me going because I am not the usual. I am weird. Why not, normal is so boring. It's just about perception or any sane being would have looked at my life to gasp in horror and call it dull, miserable and monotonous. But I feel proud when my teachers made me stand in front of the class and said, "Look, this is the student you all should try to become. I am sure you can never be like her as she is one and only. She is the best, been student of the year every year, always topped the class and every competition and this year awaits wonders in inter school board exams for her."  At noon I sat...
