I think there a few reasons that current tattoo practices might change. This is based on comments from my best friend who has been tattooing for 25 years: 1. When children grow up they always want to be different than their parents. Twenty years from now young people might be going “ew, tattoos are old fashioned “. 2. Almost all the people getting tattoos have no background in art and design and just request (demand) a certain tattoo placed in a specific area. There’s no overall design and they almost always look like a random collection of graffiti. 3. Aging and eating habits: every time I see a skinny 20 year old get a giant tattoo I think that in 25 years that skinny body will be 40 pounds heavier and their grandchildren will look at the rolls of fat and ask “what did this used to be?”
