Religious beliefs are the first limiting factor, they are so strong that they create stigmas about this art without having a valid scientific reason for that and without knowing that tattooing existed long before man created religion.
We all at some point are afraid to get tattooed because of the impediment of donating blood, but we know that it is momentary.
You can admire the tattoo without having one, thanks for sharing your opinions. @juwon-btc
