<human>: This might not be understood by a lot of you. Grew up in the mid-west. Hunting is crazy huge here. Grew up hunting all my life, and honestly, have always enjoyed it. But in the last couple years or so, I've just completely lost the passion for it, and now if feels wrong to be going out and killing something, just to do it. Its not really a moral objection, because I eat the meat and love it. Its a really hard feeling to explain, almost like jerking it, but halfway through you realize you were never horny in the first place and just give up. Or when you've beaten a really great game, but have no intentions of picking ip up again. Sort of a mixture of those two feelings   

But heres the thing, and whats making it difficult... It's my dads entire life. He's like Ted Nuget minus the music (ALL HUNTING). If he's not planning hunts, or actually hunting, he's either fishing or sleeping. Its crazy. He invests all his money into property, conservation, guns, and all hunting accessories, which he hopes to pass onto me. I know he would be absolutely devastated if I told him I was wanting to stop, or at least slow down. With him investing so much, this will also come as a financial shock. We're doing just fine, but I know he'll be upset after putting so much into it, thinking I would do this forever. 

What I could really use is some advice on how to tell him. I want him to know I still want to hang out with the guys, and do the trips, but I think my days pulling the trigger are over.

Can you summarize the given text in a few sentences?
<bot>: Dad is a hunting machine. Invests all his time and money into. I no longer want to hunt, and I know it will devastate him. How should I best approach this?
