i feel completely safe sitting down on the couch... but the reason i have to hunt is maybe, ultimately, because of the risk? if that makes any sense.
i suspect this is why whitetail hunting never really appealed to me, there's no element of danger.
There's an element of danger to anything you do or don't do in life. Just living on this Earth exposes you to dangers of all kinds every second of every day. But the truth be told I feel safer when hunting biggame. I feel safer when I hunt upland and waterfowl. I feel safer when I'm at the shooting range. I felt safer when I flew for a living. This is all in comparison to my daily commute to work now, where I'm forced to share the road with tons of careless reckful drivers twice each day 5 days a week and some weekends. As far as whitetail deer hunting goes I think more midwesterners and easterners are injured or killed falling out of treestands than any other type of hunting accidents out there. Possibly.
When it comes to scent, there are basically two types; those that attract and those that mask. I've tried both on many occasions. There are lots and lots of "doe in heat" scents, designed to attract a big buck into range. I've also used a "cow in heat" scent while elk hunting.
Another scent would almost be better named as a "coverup smell". The main goal is to cover up human odor or mask it. Though I don't believe you can ever totally eliminate all human...
