I'm already "old" by some people's standards, which is their problem not mine if they want to say I shouldn't do what I want to do because they think I'm old (and wrinkled lol).
So absolutely, I say folks who want a tat should get a tat 'cause you only live once, or twice, maybe three times, tops, or ...
That said, I HAVE always wanted to do it and haven't done so because of fear of pain.
I love the pic posted above and not because I think it is funny. I think the older version of the man is more interesting than the younger because he has had those tats for a lifetime and they are a part of him. And I DO believe his grandkids probably think he is special, even though they may not say so.
