First I would like to correct your vocabulary and the "cartilage" piercing is actually called the helix. Keep in mind that most of your ear is made up of cartilage, so to call it a cartilage piercing is a little vague. Also, for nose, it is also referred to as nostril piercing.
I personally would go with the helix piercing first. I am not a huge fan of nostril piercings. Oh, and if you do go with the helix, get it pierced with the hoop in the picture.
With the cbr (the ring in the picture) it doesn't snag on hair, which helps a lot.
You should get a cartilage. The healing process is much easier than a nose.
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.
