Violence is a destructive thing..the army protects through destruction..if you find peace in that then very well but as masochist said you should be able to attain peace by simply being peacefull...modern life is all about rushing, it would do all good to sit and just think for an hour or two. Sometimes doing nothing is the right thing to do.

On the subject of tatoos..I feel they don't really symbolize bravery anymore than getting your hair dyed..pain is pain and self inflicted pain for easthetic reasons is yet another shallow change to our appearance we think changes us..personaly i think women who get thier crotches waxed are much braver..i mean they don't even display it..my sister got coito ergo sum on the base of her spine..and she isn't brave at all so go figure..who do you do it for?
