TATTOOS

I considered getting a tat years ago but never got around to it, here is an article on them

Tattoo inks consist of pigments combined with a carrier, and are used in tattooing.
Tattoo inks are available in a range of colors that can be thinned or mixed together to produce other colors and shades. Most professional tattoo artists purchase inks pre-made (known as pre-dispersed inks), while some tattooers mix their own using a dry pigment and a carrier.[1]
Tattoo ink is generally permanent. Tattoo removal is difficult, painful, and the degree of success depends on the materials used. Recently developed inks claim to be comparatively easy to remove. Unsubstantiated claims have been made that some inks fade over time, yielding a "semi-permanent tattoo."
Regulations
In the United States, tattoo inks are subject to regulation by the U.S. Food and Drug Administration as cosmetics and color additives. This regulatory authority is, however, not generally exercised.[2] The FDA and medical practitioners have noted that many ink pigments used in tattoos are “industrial strength colors suitable for printers’ ink or automobile paint.”[3][4]
In California, Proposition 65 requires that Californians be warned before exposure to certain harmful chemicals;[5] tattoo parlors in California must warn their patrons that tattoo inks contain heavy metals known to cause cancer, birth defects, and other reproductive harm.[5]
Pigment bases
Manufacturers are not required to reveal their ingredients or conduct trials, and recipes may be proprietary. Professional inks may be made from iron oxides (rust), metal salts, or plastics.[6] Homemade or traditional tattoo inks may be made from pen ink, soot, dirt, blood, or other ingredients.[3][7]
Heavy metals used for colors include mercury (red); lead (yellow, green, white); cadmium (red, orange, yellow); nickel (black); zinc (yellow, white); chromium (green); cobalt (blue); aluminium (green, violet); titanium (white); copper (blue, green); iron (brown, red, black); and barium (white). Metal oxides used include ferrocyanide and ferricyanide (yellow, red, green, blue). Organic chemicals used include azo-chemicals (orange, brown, yellow, green, violet) and naptha-derived chemicals (red). Carbon (soot or ash) is also used for black. Other elements used as pigments include antimony, arsenic, beryllium, calcium, lithium, selenium, and sulphur.[5][7]
Tattoo ink manufacturers typically blend the heavy metal pigments and/or use lightening agents (such as lead or titanium) to reduce production costs.[7]
Carriers
A carrier acts as a solvent for the pigment, to “carry” the pigment from the point of needle trauma to the surrounding dermis. Carriers keep the ink evenly mixed and free from pathogens, and aid application. The most typical solvent is ethyl alcohol or distilled water, but denatured alcohols, methanol, rubbing alcohol, propylene glycol, and glycerine are also used. When an alcohol is used as part of the carrier base in tattoo ink or to disinfect the skin before application of the tattoo, it increases the skin's permeability, helping to transport more pigment into the skin.
Health concerns
A variety of medical problems, though uncommon, can result from tattooing.
Medical workers have observed rare but severe medical complications from tattoo pigments in the body,[8] and have noted that people acquiring tattoos rarely assess health risks prior to receiving their tattoos.[9][10]
A recent case report also showed that tattoo pigments migrate into lymph nodes. These can show up on some types of medical scans as tumors. One woman was given a complete hysterectomy only to find out later that the lymph nodes contained tattoo pigment.[11][12]
Other tattoo inks
Glow in the dark ink and blacklight ink
Both blacklight and glow in the dark inks have been used for tattooing. Glow in the dark ink absorbs and retains light, and then glows in darkened conditions by process of phosphorescence. Blacklight ink does not glow in the dark, but reacts to non-visible UV light, producing a visible glow by fluorescence. The resulting glow of both these inks is highly variable.
The safety of such inks for use on humans is widely debated in the tattoo community.
The ingredients in some "glow" inks are listed as: (PMMA) Polymethylmethacrylate 97.5% and microspheres of fluorescent dye 2.5% suspended in UV sterilized, distilled water.
Removable tattoo ink
While tattoo ink is generally very painful and laborious to remove, tattoo removal being quite involved, a recently introduced ink has been developed to be easier to remove by laser treatments than traditional inks.
Black henna
Health Canada has advised against the use of "black henna" temporary tattoo ink which contains para-phenylenediamine (PPD), an ingredient in hair dyes. Black henna is normally applied externally in temporary Mehandi applications, rather than being inserted beneath the skin in a permanent tattoo.
Another ink may be used instead of black henna. "Jagua", a fruit based ink proven to be a healthier alternative to black henna.
Allergic reactions to PPD include rashes, contact dermatitis, itching, blisters, open sores, scarring and other potentially harmful effects.[13]
Vegan tattoo ink
Various tattoo ink manufacturers also produce vegan-friendly inks that do not contain any animal by-products like bone char, glycerin, gelatin and shellac.[14]
Ancient Roman recipe
The Roman physician Aetius created a recipe for tattoo ink:[15]
One pound of Egyptian pine bark
Two ounces of corroded bronze, ground with vinegar
Two ounces of gall (bile from gallbladder)
One ounce of vitriol (iron sulphate)
Mix well and sift. Soak powder in 2 parts water and 1 part leek juice. Wash the skin to be tattooed with leek juice. Prick design with needles until blood is drawn. Rub in the ink.

Tattoos I can somewhat understand if one belong to a certain group, occupation or culture that have specific tattoos as their “trade mark”. The Yakuza, Sailors, or aboriginal Polynesians for example. Just to put on som sleeve tattoos because David Beckham started a fashion trend of it I don’t think is cool.

Got one a few months ago (aged 47) on the majority of my lower leg, love it. It combines the flower of life with yin yang symbol wrapped in a bad boy dragon.
5-6 hours under the needle was tough, but glad I did it. I'd had one small one near my ankle for years, and I no longer liked it at all, so partly was to cover that over. The one I have now is quite big and it has kind of given me the bug for it. I wouldn't mind something on my arm now..

Being trained as an acupuncturist I am totally against it or piercing for health reasons
Saying that I can appreciate the work of horiachi or Wendy Pham
Most tattooists are mere amatures
Don't put power into the form let it naturally arise from the form

It does take a while to heal and you're basically walking around with an open wound. It wasn't nice for a while and you need to take good care of it. I was lucky I had a guy with years of experience, but it definitely pays to do your homework and research as there are plenty of ways it could go wrong.. Just whilst I was there I heard a few dodgy stories about the previous owner of that particular parlour.
