Reddit user u/CasualBeers recently asked, "What’s some basic knowledge that a scary amount of people don’t know?"
Here are the top-voted responses:
1. "People living alone should learn how to do a Heimlich maneuver on themselves and also teach themselves some basic first aid. It could save your life when you have no one else around."
2. "How to tell if food has gone bad. When I worked in a meat department, we got like one call a day from people saying 'I bought this X days ago, is it still good?' Lady, I’m not there with you. This ain’t a smell-o-phone. You’re going to have to use your own senses and brain on this one."
"My mom will always use meat before the date on the package and refuse to use meat even one day after. It's infuriating. I've had too many conversations that go: 'Man, this bacon doesn't taste right.' 'Yeah, I know, it smelled funky in the package, too.' 'Then why did you cook it?' 'It doesn't expire until tomorrow.'"
3. "Don’t dive in the water to save a drowning person. They WILL kill you or you could injure yourself. Throw them a flotation device. Hand them a broomstick and pull them to safety. Do NOT get in the water with a panicking person. Wait until they are unconscious and then safely get in to retrieve them."
4. "Do NOT pour water in hot oil and NEVER put out a grease fire with water, either. Schools should at least have one class or program highlighting the common risks at home and the methods to avoid and contain them."
5. "Antibiotics do NOT work on a virus. My mother-in-law gets them for a cold. She takes half a pack and then saves the rest for later. You should finished them, even if you start to feel better. She even offers them out to us when we’re sick. (We don’t take them, of course). She has a whole lunch box of old random antibiotics up in her cupboard. I’ve tried to tell her multiple times she’s doing it wrong, but what would I know? I only worked in a pharmacy for six years."
6. "That pretty much every machine requires maintenance. Think dishwashers, washing machines, cars, mowers, etc. They aren't magic boxes. And they will last longer if you know how to maintain them. My mother-in-law is in her eighties and until recently didn't know that the dishwasher needs its filters cleaned every so often."
7. "How to merge in traffic. Specifically, zipper-merging. People are terrible at that."
8. "How to spot an obvious scam. That's why I'm offering a $5,000 course on how to avoid scams! Enroll today! If you haven't learned what a scam is by the end of the course, money back guaranteed!"
9. "Everyone should know where their water shut-off is in their house."
"Also, everyone should know that turning off the water doesn't magically depressurize your pipes. If you've got a leak or are DIYing some plumbing, you need to open up faucets so the water already in the pipes drains out."
