Thought it might be good for those considering tattoos to read this first, and maybe reconsider their design! (Go with thick lines, less complex pictures, and keep it out of the sun!)
Ian Eames, a researcher in fluid mechanics at University College London, has created a mathematical model which can be used to predict the movement of tattoo ink particles over time, and give an idea of which designs age better. The paper, which is published in the Mathematics Today journal, will enable those considering getting a tattoo to accurately predict how their design will look in 20 years' time.
Eames said the study would "pave the way towards assessing whether there are any long-term health implications" and provide "an idea of how their chosen design could look several years down the line".
Tattoo inks are a suspension of water-insoluble particles, such as mercury, lead, cadmium and iron, which are injected under the skin using a needle. Over time, these inks become dispersed as the cells which contain them die, divide or leave the body.
"Skin type, age, size, exposure to the sunlight and the type of ink which is used all influence how a tattoo disperses with time," explained Eames.
"Now, more than ever, the illusions of division threaten our very existence. We all know the truth: more connects us than separates us. But in times of crisis the wise build bridges, while the foolish build barriers. We must find a way to look after one another as if we were one single tribe.” -King T'Challa, Black Panther
The truth is incontrovertible. Malice may attack it. ignorance may deride it, but in the end, there it is. ~Winston Churchill
