Since time immemorial, smoke signals have been used for long-distance communication to convey danger or the need for help. Even today, when peoples’ cars break down in the middle of nowhere, they use flare guns to signal others. But what if your car breaks down at the most unexpected of places and you either do not have a flare gun or have exhausted the flares?

In that case, the best bet is to burn a spare tire and release that large column of black smoke. The smoke would alert people miles away. Someone is bound to pick up the smoke as a cry for help and come to rescue. But before a tire, you must ensure that it’s punctured and has the valve core removed so as to avoid abrupt explosions.

7. The best defense against an aggressive bear is to not run away from it but to get a large object and keep moving it by keeping it between the bear and you. This will either scare or tire the bear and make him leave.

The best way to defend a bear attack is to avoid it entirely! But if and in case you get caught in an encounter with a bear, then there a few things that you should keep in mind. Firstly, never try to run away from a bear, because no matter how fast you run, the bear will catch you and see you as a threat. Most of the times, bears are just curious. and the best way to deal with them is by slowly taking steps away from the bear.

Another defensive technique against an aggressive bear is to use objects such as a chair or a big stick to make yourself feel bigger. If there is a big tree or a car nearby, get behind it and keep moving around it. The bear will get bored or scared after some time and might decide to leave you alone. Whatever you do, never run away from an aggressive bear. Also, remember to always have bear spray in hand if the area you are about to visit is marked as a bear-sighting zone. (source)

8. An unconscious diabetic person should never be given insulin. If in doubt, giving sugar is the best option.

The most common emergency in case of diabetics is their sugar level has gone below the recommended threshold. When blood sugar drops too low, the person might feel drowsy and even lose consciousness. There are numerous reasons for the sugar drop. The person must have taken too much insulin, they might have not eaten properly or skipped a meal, or they might have exercised without a proper diet.

Whatever the case, if you are in the company of a diabetic person who either gets drowsy or unconscious, never deliver insulin under such scenarios. Extra insulin would only lead to a further drop in the blood sugar. The best option would be to give them sugar or a sweetened item to raise the blood sugar level. (source)

9. If you get sucked into a rip current and are dragged away from the shore, never try to swim towards the shore, i.e. against the rip current. The best way to get away from the current is to swim parallel to it, get out of the current, and then turn back towards the shore.

A rip current is a fast-moving narrow channel of water that starts at the shore of the beach and extends to a distance offshore. If you get caught in a rip current, stay calm. A rip current never pulls the person underwater. It just takes the person further away from the shore. Most people start to panic at this time and try to swim against the current. But the best bet would be to avoid doing that. Trying to swim against the current will just tire you out. Try to swim parallel to the rip current and get out of it. Then you can turn and make your way to the shore with the help of the breaking waves.

If possible, try to identify rip currents and stay out of them. If there’s a break in the middle of a wave or the sea has an unusually still section of water, then it’s best to stay away from it. (source)

We get cranky when we see red eyes on photographs. But getting red eyes in photos is a healthy sign. The red-eye-effect is caused when the camera captures light being beautifully reflected by the eye’s retina when a flash is used for capturing photos in dim-light situations. The red is because of the blood supply that nourishes the retina. This means that when you get red eyes in photos, you have a healthy retina.

But in some cases, especially in the case of children, instead of red eyes, they get white or yellow eyes in photos. Such a glow can be a serious health alert. The person or the kid might be suffering from cataract, eye infection, Coats’ disease, or retinal detachment. It is recommended to seek medical help as soon as possible. (source)
