I lost interest from about 24 until about 38. Not because I didn't want to, but because I lost my fishing spots, and other things got in the way.
Bass fishing is not my only love, and for a long time, guns/reloading/casting took top priority. Now they sort of share.
For me, fishing is a part of the love of the outdoors. I want to impart that love to my boy, so, fishing is very kid friendly, but guns aren't as much. He does love to watch me shoot clay pigeons, but he doesn't get to shoot yet since he's only 4. He can however cast and reel, so fishing is more his speed.
