What’s the next step after you’ve had 70 per cent of your body covered in tattoos?
Getting your eyeballs tattooed, obviously.
So that's exactly what Rodrigo Fernando dos Santos did.
“I cried ink for two days. Only now is the color of my tears lightening up. I think they are still half gray,” the 39-year-old, who is also a tattoo artist himself, told Brazil's The Local.
He paid fellow inker Rafael Leao Dias nearly £350 to do the eyeball darkening.
“There is no drilling," Dias said, according to MyHealthBowl.com.
"We apply the ink between the conjunctiva and sclera layer that protects the eye. I studied the procedure for two years and performed my first application in October 2012.

“The law does not prohibit this, here or abroad. There is no risk or discomfort due to the use of specific eyewash."
The procedure sees the use of a special syringe-like needle that injects ink into the eyeball permanently.
There have been reports of eyeball tattoos up to 2,000 years ago, according to an FAQ on the trend by BME.com which stresses blindness as a potential risk.
Vancouver-based body modification artist Russ Fox told The Huffington Post the injection method originated in Toronto around six years ago.
"The contrast and relationship between a person's natural iris color and the scleral tattoo can create all sorts of amazing and beautiful effects," he told blogger La Carmina.
"For example, tattooing the sclera solid black will have differing effects if a person has crystal blue irises as opposed to dark brown irises. Brighter colors have drastically different effects."
