I asked this question because I missed a healthy doe the other day because (Well, I think because I was holding my bow back too long) i got buck fever supposively. I had held my bow back for at least 3 minutes and my knees quivered and shaking. Iam glad I had a shot(my first one ever), but I guess I was too scared that I would spook the deer if my bow made a sound when I released it.
