If your vomit ever looks like coffee grounds, you are bleeding internally and need to go to the ER immediately.

For bears there is a rhyme. If it's black, fight back. If it's brown, lie down. If it's white, say good night. In the case of black bears they're generally smaller. If one is attacking you then you have a chance of survival by fighting back. You'll probably be in awful shape but you'll live. In the case of a brown bear, it's best to show it that you are not a threat to it or it's cubs. Lie down, protect your neck and head. Make sure it's gone before getting back up. In the case of polar bears things are very different. If you notice a polar bear hunting you then it's already too late. Make peace with your gods because you are going to die.

if you ever need someone to call 911, make sure you specifically point someone out of the crowd of people. "you in the red shirt, call 911". if you don't, nobody will because they assume someone else will

Heart attack pain for women is often different than men. The classic symptoms of chest pains radiating down your left arm isn’t what most women feel. It’s often a chest tightness, horrible gastric reflux feeling, and an impending sense of doom. It’s also described as the worst pain you’ve ever felt and women don’t go to the dr for it bc “childbirth was worse” etc. So women, don’t ignore any sort of tightness, pressure, or twinges in your chest.

Driving tired is just as dangerous as driving drunk. I got up at 4 am to make a 7 am flight from Toronto to LA, but I got bumped, and routed via Vancouver instead. Instead of getting into LA at 11 am local time, I ended up getting in at 4 pm, and hit a massive traffic jam heading south. This was before cell phones so I had no traffic info that I understood, and I just stayed on the highway. By the time I turned off the highway, I'd been up for 20 hours. I could feel my head falling as I micronapped and jerked awake, but I had only a few miles to go, so I kept going. Bad move. Another micronap, crossed the median, and hit another car. Just a broken foot for me, and a few bruises for her, but it could have been much much worse. If you're that tired, pull off and sleep.

In the US, by law, every cell tower has to receive and connect 911 calls. It’s entirely possible that your cellphone says “no signal,” because you’re not in range of your specific network and you have roaming turned off, but if needed you could call 911 without any issue at all.
