Fatigue itself shouldn't cause fever, as it is really a symptom, not a cause, however being fatigued definitely leaves you less able to defend against illness, and an oncoming fever or illness make...
From the coasteering excursions I and my family have been on in Scotland, the rest of the UK and some other European countries, there appears to be no consistent grading. What I have seen is use o...
This one is actually much simpler than you might realise: On a three feathered arrow, the nock is at 90 degrees to one feather, and at 30 degrees to the other two feathers. If the cock feather wa...
This is all information you can get from a plethora of online sources, but from a quick 2 minutes I found this: for Grenoble, a 20cm snowfall is a high average. Temperature change between day and...
According to what I can find on Wikipedia and elsewhere, it looks like it was in the 1880s. Before that, bolts had been used as climbing aids. Best candidate for first climber and route is W.P. Ha...
If we exclude the birdwatching explanation Shem gives, the only possible ecological reason for a bird feeder is to counteract the negative effect we have on the bird's habitat by having our house t...
Condensation is usually caused by high humidity combined with a temperature differential. It sounds like you have a very humid atmosphere, which in a tent is added to by the high moisture content o...
One aspect not yet touched on is that for beginner climbers, upper body strength is not actually as important as you might imagine. If we exclude overhangs (which is reasonable for early stages of ...
The three risks that are relevant here are the risk of fire, suffocation and carbon monoxide poisoning I'll take suffocation first. A gas leak can exclude oxygen to the point that you can no longe...
There are a few aspects: Collision: some birds are better than others at avoiding wind farms, but this is a risk. Noise: the noise from the turbine and blades unsettles and upsets animals and bir...
The original meaning was the weight of the water displaced by the hull, but typically the hull weight is used to mean just the weight of the hull - minus fittings etc. Hopefully that helps solve...
Red has been covered already, and it really is the most practical colour to have with you at night, as it is the only one that doesn't impact your night vision significantly. The others, though, a...
Typically, using 3/4" (19mm) plywood board is strong enough for this use. And the bolts you want are 3/4" (19mm) plus enough each end to screw into the hold and to accept a nut. Bolts used for mos...
If your reason for not wanting camo is that you want to be obvious (maybe to other hunters so you don't get shot) then you can always flash a backpack with reflective material, or use a hi vis pack...
When learning, lying down on the board is perfectly normal, and you can surf a wave just fine like this (typically with a loss of agility as it's hard to move your body weight) and a board This hap...
The concern here would be if the helmet could move far enough that it doesn't protect your skull adequately. If you can move it significantly I'd want to sort it - remember in an emergency it could...
I swear by Thule for transporting anything on the roof. Over the years I have had various vehicles, and various transport requirements, and this type of bar has: replaceable mounts, so for the ca...
I grew up in a fishing community on islands north of Scotland, and never once heard this. The folks up there used English and Norse greetings, but not a German one, so I would imagine it is German-...
Jellyfish, while mobile, are not capable of much evasion. They can steer their bodies, but they are limited in their ability to get out of the way of a faster organism - which is why the majority r...
The ocean floor is almost entirely undisturbed by waves - What you are finding comes from the coastal littoral. You can gain some general estimates from direction and strength of storms, but the m...
Once you are past uphauling, it is not a move you are likely to use again. It is a high effort move that in high winds is next to impossible. The moves you will need to learn are: beach start tac...
If you don't have a shelter, then you want to find somewhere as safe as possible with solid walls surrounding you, at the core of your building. Garages don't usually fulfil this role, as while yo...
The simple answer is yes, you can definitely use waste paper or cardboard to stop an arrow. Various folks have used cardboard boxes, flattened, and piled up to anywhere between 6 and 12 inches thic...
For certain types of hiking, lightness is key. I can't talk for everyone doing that (some may just be unaware of the consequences of their kit choices) but I really like speed hiking / fell running...
This is why most snowboarding and skiing gloves these days have a wiper built in. Rain-X and other coatings can help a little, but there appears to be no all purpose solution, so just get a pair of...
