00:00 Tattoos have a long history, dating back to ancient times and serving various purposes, including pain relief and identification of criminals and slaves.

05:47 Tattooing was once used as a punishment in some cultures, including the Greeks and the Romans, and was also used to identify slaves and criminals, but sailors were the first Westerners to adopt tattoos and they became associated with marginalized groups and fringe dwellers until the 70s or 80s.

11:12 The elite of Western society adopted tattoos as a status symbol after Japan opened up to the Western world in 1853 and had remarkable tattoo artists, with the trend of tattoos among the elite being different from the tattoos of criminals and fringe dwellers.

16:47 During the 1960s, tattoos were forced underground and made illegal, but were taken up by fringe groups like biker gangs and Chicano gangs, becoming associated with these groups especially after the Zoot Suit Riot.

22:09 Tattoos have become increasingly mainstream and tolerated, with a prediction that they may become passe in the next few years due to the high number of people getting tattoos, and new trends include UV sensitive inks and 3D nipple tattoos for breast cancer survivors.

27:41 In prison, tattoos are often done using makeshift tools and materials, such as toothbrushes with staples, pen ink, and melted styrofoam, and they usually have significant meaning related to gangs or personal associations; however, in a professional tattoo parlor, a tattoo gun invented in 1891 is typically used, with newer models using compressed air for sterilization, and artists must consider factors such as needle depth and artistic techniques when tattooing on human skin.

33:26 In a professional tattoo parlor, the artist will draw or stencil the design on your skin before tattooing, starting with outlining in black work, then moving on to shading and coloring, with each step requiring cleaning and wiping off the tattoo, and the pain level varies depending on the individual and the location of the tattoo.

38:45 After getting a tattoo, it is important to follow proper aftercare instructions, which can vary depending on the tattoo parlor, but generally involve keeping the tattoo clean, avoiding submerging it in water, and applying lotion or ointment as needed.

43:59 When getting a tattoo, it is important to find a skilled tattoo artist who can create the design you want and ensure the tattoo stays sharp and doesn't fade over time, as well as prioritize safety by choosing a reputable tattoo parlor that follows proper sterilization and sanitation protocols to minimize the risk of blood-borne pathogens or skin infections.

49:37 Tattoo ink is not regulated by the FDA and can contain metallic pigments that can cause burning during an MRI, and cosmetic tattoos like eyeliner can mess up an MRI of a person's brain.

54:53 Black henna tattoos can contain synthetic ingredients that can cause permanent scarring and bad reactions, so it's best to use natural orange henna instead.

01:00:27 Laser tattoo removal is a common method used today, but it can be expensive and may require multiple sessions depending on the color of the tattoo, and there are other options like microdermabrasion available as well.

01:06:13 Bagel head body modification, where a round protrusion is created on the forehead, is a strange trend in Japan that is gaining popularity.
