Never go out in the woods where wild hogs roam w/o a handgun. being caught on the ground by a herd sucks
NEVER EVER wear an elastic wading belt when wading/trout fishing. That one damn near drowned me when I went down face, and open wader top pointing upstream. The elastic belt just stretches and you fill up with water - FAST. And it is HEAVY! Also never let anyone else use elastic belt.
One thing I will ALWAYS do is wear shooting glasses. Very first black powder trigger I pulled, at age 16, cap splintered and hit my shooting glasses. I would be blind in my right eye had it not been for those glasses. Still have the scar where the cap slide off the glasses and cut my face.
