According to article Benefits of Copper, Orange, Yellow And Brown Lens Tints and from my own experience, but with cycling solar glasses: Copper, orange, yellow/amber and brown lens tints make a...
As background, I've hiked the Kungsleden in 2014 (my second hike, and first self-organized), as well as both marked trails and cross country in Norway and Iceland. To add to the risks already menti...
Having tried all known expensive remedies to little effect, here is one that was recommended by a friend: equal parts of tap water & apple cider vinegar plus a few drops each of rose geranium a...
Not going to distract with an axe and then climb a tree. You got to the tree or not before the hog got to you. Hogs are usually in brush without a lot of trees you can climb. An axe is a formida...
Bring one change of dry clothes to change into when you are in your overnight cabin, all the way from top to toes and from the skin out, and make sure you have enough layers to be warm when there i...
Seems there is a lot of research done. I found this article which cites a lot of interesting resources. I could not retrieve precise numbers. They published a code of best practice, but they say al...
Your question made me wonder how Robert Falcon Scott wrote his final diary entries on his trip to the South Pole in 1912. This article, from The Guardian, Scott of the Antartic's final diary pub...
You could use a combination of stitching, to stabilize the cut edges, with a generous application of Freesole or Shoe Goo both outside and inside. Both are flexible enough to hold and the stitching...
That is a cog, A cog is a type of ship that first appeared in the 10th century, and was widely used from around the 12th century on. Cogs were clinker-built, generally of oak, which was an abun...
A tent's UV resistance isn't for you, it's for the tent. High-energy UV rays will break down many synthetic and natural textiles over time. UV resistant fabrics are not as susceptible to this break...
It's because the sunlight will damage the tents fabric over time. UV damage occurs when long term exposure to the sun damages the fabric and thread of your tent or rain fly. The fabric will bec...
Down will inevitably pierce through thin fabrics (an thicker ones too, just less frequently). It's in the nature of quills to do so and even if very fine, there are quills nonetheless. The lighter ...
It's a military Cogue/Cog/Koggen with fore and aft archery towers. Cogues are the only medieval single mast square rigged sailboats of this style.
Very indoors, shut up tight, and at a suitable time of day. If you live in a house (as opposed to a flat), and it has reasonably good insulation and tight-fitting windows, the high-pitched sound o...
There is actually an international standard for this: The Chicago Convention on International Civil Aviation, and in there Annex 12 – Search and Rescue, appendix 2 "Ground-air visual signal code". ...
With suitable preparation, photography can be more useful than you currently realise. The trick is to make yourself some props to communicate the data you need: For species identification, make ...
Let me suggest that some acclimatization may help (though I'm not sure how practical this is). I was personally rather astonished how much we can actually adapt to cold weather: I spent a winter...
You asked two questions: How does it balance, and why does it do this? Charlie answered "Why does it do this?", and he did so quite well, especially since, as his sources suggest, even the biologis...
I would suggest a pair of good waterproof winter gloves instead of mittens. These will keep your hands warm and protected from wind and still allow for enough dexterity for writing with a pencil.
This is called gaze stabilization and birds do it to keep one thing in focus even while their body is moving. What is head stabilization in birds? When the body of a bird is held in the han...
It is for two reasons. By far, the primary concern is that UV rays will make the textiles deteriorate over time. UV resistant textiles will last a lot longer, and deteriorate less from only sunligh...
Think of the basic triangle - you need warmth, dryness, and wind-free. OP's question does not mention being wet but does reference the cold AND the windchill. So limit the wind with some kind of ...
It doesn't matter. Blowing a whistle is not an emergency signal: emergency signals have a certain sequence. Be sure to use your hands to close your ears (index fingers pressing ear canals closed)...
I would largely agree with the previous response. However, most bird bath heaters (a site I`m affiliated with) today do not get hot enough to melt plastic. If you have a plastic or resin bird bath,...
When I worked at a salebarn in the winter we had this problem and the solution was multiple pens inside your shirt pocket under your coat. Pens will work for a while then get too cold at which poi...
