Driving through standing water. Just because the car in front of you makes it through doesn’t mean you will.

Do not attach two very active dogs to the handle of a Razor scooter because you want to see if they'd be good sled dogs. .

Women who warn you that they are crazy... She is indeed crazy.

Just because you climbed up something doesn't mean you can climb down.

Hiking alone in Iceland being a confident hiker. Paraphrasing: the most dangerous hiker is a confident hiker. I got lost, didn't pack enough food and got caught on the side of a mountain. 20 people had to rescue me. Never again.

Not wearing hearing-protection when necessary. Tinnitus sucks.

Customs officers. They have no sense of humor, don't ask me how I know.

First responder here. Garage door springs. Let a pro fix them.

In ground yellow jackets. Pay the dude with the bee suit and the right s**t to kill them safely.

Don't work full time and go to school full time.

Dehydration and overheating. Being covered in ice in an ambulance and pissing black pee will change your perspective.

Chainsaws. I don’t even like the sound anymore. I had an accident with one and cut up my leg.

If an older man has a "saddle nose deformity" or cauliflower ears, let them be. A saddle nose deformity nose is also called a "boxer's nose". An old man with training will f*****g kill you. That's how they got to be old.

Sleep deprivation. Damn near died in a car accident (round 1), then went mildly psychotic and paranoid (round 2). Just dumb. There are better paths to adrenaline-fueled euphoria.

Road rage, I was chased by a guy threatening me to shoot me, that was the last time I yelled at somebody while driving.

Pedestrian safety. Was hit by a car crossing the street. After cpr onsite and coma in hospital had to learn to walk and talk all over again. I triple check both ways. Even when I have the right of way.

Taking sleep meds (ambian) and laxatives (myralax) within the same 24hrs. What a nightmare!

Paying my taxes. Worked for myself through college and didn't have a penny to spare so I just didn't file for three years figuring I'd pay it off when I was done and working. Ironically, my first job after graduating was for the state tax and rev dept. They figured it out lickety split and gave me a month to make good. Paid some pretty serious interest and penalties and learned to never do that again.

Don't f**k with the ocean, I got swept away by a wave while stupidly sitting on a rock too close to the water. I thought I was a goner and never to be found again but then it got tired of me and thew me back towards some rocks like a used intimate hygiene tissue.

Cars in snow. You ever seen a video where someone does a 360 in the snow and hits something? I did that and got lucky the thing I hit was a curb.

Moose. If they decide they don’t like you, they can f**k you up. Only orcas get to mess with them.

Oral health. Brush your damn teeth or you’ll sorely regret it later

Electricity.
