Wild dogs can indeed be dangerous, and packs can be extremely dangerous. You do not want to take on a pack of dogs if you can at all avoid it, and running is often a particularly bad idea. I suggest starting with the basics: try to keep the dog calm and don't try to intimidate it. This means: Don't make direct eye contact, and remember that sunglasses ...

No you should not use a bicycle helmet for climbing. They are designed for different types of impacts and will not provide you with proper protection outside of their designed activity. Bicycle helmets are designed for a SINGLE ground impact. Like modern cars they are designed to crumple and absorb the energy from an impact. They probably provide the ...

There is no specific distance from which a person can fall and have it said they will survive or not survive. There are simply too many other variables that will dominate the factor of "distance." In 1971, flight attendant Vesna Vulović fell 33,333 ft (10,160 meters) and survived without a parachute. On the other hand 556,000 people died in 2013 from slip-...

When you're asking for the safest way to purify water, you're asking for the method that removes the most harmful stuff from the water, like bacteria, viruses and larger impurities like mud or sand. No one method is really perfect at removing everything, so I usually use a two-stage approach: Filter: If the water source is cloudy, your first step should ...

Anybody who has severe allergies which could lead to anaphylaxic shock should carry appropriate medication with them. Typically, that would consist of: An antihistamine (e.g. benadryll) An epinephrine auto-injector (aka "Epi-Pen") Benadryll is available over the counter and you should have it in your first aid kit. Epi is by prescription only (at least ...

It is of course possible, but definitely not something I would recommend. The most common method for repelling without gear is the Dülfersitz method (invented by climbing pioneer Hans Dülfer). It involves wrapping the rope around your body in such a way as to allow you to better control your descent. The rope first goes between your legs front to back, ...

In the UK (we don't have many dangerous animals) cows are the most dangerous animals you're likely to come across. They kill about a dozen people every year. Typically most deaths are caused by herds trampling people/farmers. A lot of people are wary of bulls. In my experience a herd of mother cows is more dangerous, especially if they cows think you are a ...

The short answer is "bear spray"; a firearm is really not the most effective option. That said... I will assume you are looking for grizzly protection, since you didn't specify the bear and black bears are relatively shy. Again, using spray is a far more effective way of improving your odds; a review of its use in Alaska found a 98% success rate, with no ...

Until just a few years ago I would have said tweezers. I use a tick key these days because it removes without squeezing the tick. I get between three and a dozen ticks a year (they like me), and I much prefer this to the tweezers. The big downside with tweezers is that you are compressing the tick's body and thus forcing liquid out of the tick and... ...

Assuming you don't have a genitourinary tract infection, fresh urine should be sterile, the problem is that it is a waste product which, apart from making it not taste very nice, means that consuming it will increase the concentration of waste in your body which will require an increased volume of water to absorb and subsequently excrete, resulting in you ...

It's not the fall that gets you, it's the sudden stop at the end. The most detailed data on the effects of large accelerations (or equivalently, decelerations) on the human body comes from research into spaceflight and aircraft ejection systems. There is a very detailed paper from NASA here, from which figure 5 (p. 36) is most useful. The summary is: it ...

Use tweezers, grip as near to the head as you can, and pull gently and evenly but firmly - it should come off cleanly. If it doesn't then be sure to remove the head rather than just leave it in there. Then clean the area with alcohol and be sure to keep an eye on it in case any rashes or other untoward symptoms appear. The likelihood of this depends on the ...

First, you won't need to make this observation if you routinely drink when you stop to rest, and if you eat something at least slightly salty whenever you snack (if your snacks include jerky or salted nuts you're more than covered.) Second, pay attention to your thirst. Many of us ignore our bodies for hours at a time - postponing bodily functions during a ...

To the question of whether you should run from a pack of dogs that may be aggressive, the answer is an unqualified NO!. As to what you should do, the answer is a bit more complicated. In the vast majority of cases, dogs won't attack you without provocation. As always, assume the best but prepare for the worst. The basics: Be Prepared: Prevention is ...

TLDR: Foxes do not attack humans. So you can go there day and night. To me this sounds more like a spooking story than reality. Foxes hunt very small animals, humans are way too big for them. Anyway, in their natural habitat they are extremely shy and will run away from you most likely before you are even aware of its presence. Foxes with rabies can lose ...

The question asks for an instance where a bear climbing a tree attacks a human. I found a news article of a hunter being attacked by a black bear in a tree. I don't think this is a completely satisfying answer since the question implies the question: Why would a bear expend the effort to climb up a tree to attack a human? I am not a bear expert but I read ...

Dehydration will very quickly reduce your ability to undertake the activities required to survive and so finding and conserving water should be a very high priority in any survival situation. Clearly there are potential dangers associated with drinking contaminated water but these need to be weighed against the dangers of dehydration. As with most survival ...

I personally had a similar sort of a question when I first went through similar kind of stats about these mountains. Getting introduced with these stats is different than totally understanding the mountain and the pandora box it opens. For getting acquainted with the reasons for so many failed attempts, one needs to read tactical data and expedition reports. ...

Copy and paste from the answer here: http://skeptics.stackexchange.com/questions/1540/is-it-a-good-idea-to-drink-your-own-urine-in-a-survival-situation Summary: You can do it, as a last resort, but it's dicey. The US Army doesn't think it's a good idea and lists it on its "Do NOT drink" list, stating in its Field Manual that it "contains harmful body ...

I'm answering my own question to share some knowledge. First, cold toes/fingers is serious. You start feeling discomfort, then a little pain, then you stop feeling them and forget about them, then you get them amputated. So you should constantly check if you can still feel toes and fingers, and if not, start to warm them up. Second, I find most effective ...

It is likely caused by iron in the pump or pipes. According to the Illinois Department of Public Health: Iron is mainly present in water in two forms: either the soluble ferrous iron or the insoluble ferric iron. Water containing ferrous iron is clear and colorless because the iron is completely dissolved. When exposed to air in the pressure tank or ...

I'd say the only circumstances where you could try to run is when a safe place is near (your car, some kind of shelter, a tree you can climb etc.), the dogs are already alert and running to you (otherwise you could just walk to the shelter without them noticing), and you can realistically make it to the shelter before the dogs do. Remember that dogs car run ...

How much sea water can I safely drink? = None If you drink sea water, how much fresh water do you need to drink to off set the sea water you drank? = 2.8 units of distilled water per 1 unit of sea water (to neutralize without adding hydration) The "scientific" answer to this question involves a lot of complex math, human physiology and significant ...

I've never taken an unpowered, hand-built raft out onto a commercial river, but I do have experience under sail and under power on the Columbia River in the United States. What I know about maritime law, tradition and etiquette might not be exactly what they expect in Europe, but I imagine the principles are much the same. In most cases, a craft without a ...

First of all, DO NOT bring anything smelly into your tent. This includes food, tooth paste, deodorant, or anything else that has a smell. Also, keep fires away from the tent. I recommend setting up a bear triangle campground. Cook your food in one corner, close to that corner–maybe 50 feet away–set up a latrine area. About 200 feet or more away from both, ...

So far all of the answers are assuming the wild dogs are actively hunting you or at least seriously considering attacking you. This might be due to the part of your question where you say: ... or should I stand fast and defend myself? If the dogs appear to be actively hunting you then a controlled exit to a safe area as suggested by Dmitry Grigoryev is ...

If you want a natural solution, try lemon eucalyptus oil. Considering that B1 does not deter mosquitos, any dose you like will be comparable to 75mg (zero effect). However, if we wish to assume it works, you'll want the patch. Eating B1 won't help much. Since B1 is principally excreted in your urine, eating a lot of it would only really help if you ...

Cheese: Long time. Especially hard cheeses. You can just cut any mold off the edge that might creep up. Cheeses sealed in cheese wax (gouda) are a good bet. I've had extra-sharp cheddar un-refrigerated in the AZ desert for 8+ days, in the rocky mountains for 15+ days with no issues (aside from sweat.) Blocks last longer than a pile of shredded cheese. Be ...

TL;DR - First try to identify if the wire is supposed to carry electricity (insulators on posts/wire goes to an electrical box/posted warning signs/ect...). There's really not much you can do to check the wire for current without a device aside from listening to it, touching it (potentially dangerous), or throwing something onto it that might react to a ...

When a rattlesnake gets his rattle on, what exactly is the desired reaction it's expecting from you, and what other indicators does it give you that a strike is imminent? It's a warning that it's there, it's not necessarily a warning that it's about to strike (though of course, it could.) Likewise they won't always rattle before they strike. However, bear ...
