The only time I thought that tatooes were helpful, was when there was a threat made and the women stated that the person had tatooes on his hands. So at least we knew to be on the look out for a possible altercation and a heads up to call security.
Call me old fashioned but most of us were born with clear pure skin. Then it is defiled with sonsensical drawings which look horrid after a few years. I have never seen any postive reactions to tattoes. I have only seen a few within good taste and it is usually honoring a lost loved infant or child. It for the person themselves to be reminded of the child they had , NOT for attention seeking behavior like the 99% of the other tattoes.
With all this being said, none of my children or grandchildren have any because they all have the capability to think beyond today.
