My new list

One of the great/awful things about working at a hospital is that you get to see the consequences of others' mistakes. I was told when I started at this job that I would quickly start noting to myself things I will never do, and it's true, I've got quite a list already, with five major categories:

First, some of the more serious/grim ones:
1. No guns in the house. Ever. Even if they're locked up.
2. Never ever ever attempt suicide, even if it is just a "gesture" and you didn't really mean it. Because it's bad no matter what the outcome, but if you "fail" and survive, life is not going to be any easier with those new injuries/disabilities.

Second, practical advice you might not have thought of:
3. If you have any chronic medical conditions, like diabetes or obesity, do what you can to get those under control. Because a simple broken leg can turn into something seriously nasty if you don't.

Third is the "Lots of people do it but that doesn't make it a good idea," category:
4. Never forgo your seatbelt, even if you are going 5mph on gravel with no other cars around.
5. Never ride a motorcycle. But if you insist, do it only at reasonable speeds, wearing a helmet, completely alert and sober.
6. Never ride a dirt bike. Or a motorized street bike.
7. Never ever ride a 4-wheeler.
8. Never, ever, ever, ride an ATV.

Fourth is the "Seriously, what were you thinking?" category:
9. Don't weld while drunk.
10. Basically any kind of fire + drunk = really bad idea.
11. Also don't climb trees drunk.
12. Ditto for telephone/electrical poles.
13. Don't dive drunk. (Or drive drunk, but we all already knew that).
14. If you work a night job, which means you're really tired during the day, don't take a second job (during the day, when you're really tired) that involves working machinery, like oh, say, a meat grinder.
15. Never ever ever disable any of the safety features on anything, like for example, power saws.

And finally, the "Wait... what?" category:
16. Never get yourself into a situation where your pants catch fire and you are too drunk to notice.
17. Never try to launch a large object with a large home-made cannon. Even if you've done it before and it was really cool the first time.

And that was just from my first month :) I'm sure the list will grow...
