I have seen posts like this before on this site. It is a really neat subject because it is the one thing that seperates us from our prey (we have remorse, they do not). A tiger does not feel remorse and nor does a lion when they kill. Someone once said to me that a lion would not kill just to kill and I found out this comment is untrue, they will and do out of instinct (just like a house cat does and drops it at the door step) If you think about some friendly rivaly between friends on who got the biggest buck or the most deer that year you may see a connection. Or the two guys arguing over who both shot the same deer and then erupts into a fight (sounds close to instinct to me) Also the heavy breathing, dialated pupils, increased pulse and adrenaline rush happens in all mammals that pursue a prey. I believe that no matter how hard the human race tries to surpress this urge to gather\hunt we won't loose it ever. It is what got us here and ultimatly will keep us here. I have to date helped 3 people I know get into hunting and it has changed there life and they cannot explane 100% why. So my advice to explain hunting as a complete outdoor package such as friends, family, camping hiking and most important being in the outdoors relaxing and reflecting.
