I have two brothers, one older, one younger. My older brother and I were hunting as soon as we could carry a bow and BB gun.
Of the two of us, I was the most extreme. From age 5 through my Feshman year in HS I spent every possible minute outdoors with a bow, BB gun, rifle, or shotgun in my hand. Rather than playing baseball with the other kids in the neighborhood, I spent my time poking around the riverbottoms. This probably would have continued through HS had I not discovered wrestling, football, track, and girls.
Through HS we both continued to hunt & fish as much as possible, even though he was in a very popular band and I was a three sport letterman, both of which took up a lot of time. Now I'm in my late 40's, he's in his early 50's. I've never quit living to hunt, and my life revolves around it. My older brother still hunts but his primary outdoor pursuit is tournament bass fishing. He's highly successful at this. We both settled in states which allow us to pursue our lifestyles.
Our younger brother never had the slightest interest in any outdoor pursuits, despite our best efforts to include him and get him interested. Essentially, his interests were (and in his mid 40's remain) comic books, drama, karioke, and over eating. He's so far removed from us behaviorily that we've often joked he isn't really part of our clan, but was left on the doorstep by gypsies. He settled in a large metro area of Florida known more for crime & drugs than anything else.
Three brothers raised in exactly the same environment, in a family and extended family that spent a lot of time hunting & fishing, and in the outdoors. Two became hardcore outdoorsmen, one developed into an oddball.
Go figure...
BTW, my son Jarad (AKA The Primate) was raised with a bow & rifle in his hand and has never turned his back on this heritage. He was raised to embrace hunting, the bow, the rifle, the shotgun, physical fitness, and sports. The skills he learned growing up now serve him as a grown man in his late 20's in the US Army, with one tour in Afghanistan under his belt and a second to Iraq on the horizon.
When my wife's grandkids visit us (they are from Spokane, WA), they practically overdose on archery, 22's, riding horses, gundogs, and fishing. My son' newborn daughter will be exposed in the same way...
