You would have to wait for it to fully heal before you can repierce it. So I would say about 6 months or so. But it could also be mostly healed by then and your piercer would be a better judge if you can get it pierced sooner.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
