Something I've noticed as the world has become a safer place is that people forget, or never learn, the most important safety rule of all. "Watch yourself."
I learned this from my grandfather as a child. His farm was not the safest place on the planet, and my mother and grandmother both swore he was the most careless man to ever exist, but I never felt uncomfortable working with him. It all starts with that single phrase.
"Watch yourself," puts the onus you. It's up to you to know where that piece of equipment is. It's up to you to make sure the jack is stable. It's up to you to know which cow will let walk on which side. It's up to you to remember to put a stick in the wheel of the manure trolley so it doesn't roll back and hit you when your back is turned.
As long as you follow that advice, you'll be okay. It's kept me safe in photo labs, on farms, at construction sites, and around trucks and forklifts for my entire life. Those are all dangerous places, especially since I'm old enough to have worked on them before there were many rules and a hardhat was just a convenient place to keep your cigarettes.
That doesn't mean you can skip the safety equipment or ignore the rules in place. Wearing the right stuff and following those rules is part of watching yourself. It doesn't stop there though. That forklift driver might not notice your yellow vest, because he's seen so many of them that they don't have much impact anymore. That hardhat isn't going to save you from a ton of falling steel. The best steel toes in the world will not protect against the weight of a four ton skid.
What I see all too often is that people put on their equipment and think they are suddenly impervious to harm. They take chances they wouldn't have otherwise taken, do things that they wouldn't have otherwise done.
The same rules apply with hobbies as with work. Watch yourself. Teach your wife and kids to watch themselves. You can't teach my mother in-law anything though, so watch her while you're watching yourself.
