Archery is now a very popular sport and hobby all over the world, but once, long ago, it was even more widespread. Every army had archers and men hunted with bows for food. Every country or every region invented its own particular design of bow and therefore, even nowadays, there are many different types of archery bows. Modern technology has meant that new varieties of archery bows are still being invented.

Some bows were invented by people who rode horses a lot. These bows were shorter, other bows were meant for long range shooting and these bows were longer. I will list some of the main types of archery bows below with a short explanation of each

The traditional Welsh or English longbow was made from a single length of yew (or other wood) at least the size of the bowman, but up to about six feet six inches (two metres). It was ‘D’ shaped in profile with the flat, bark side, facing away from the string. The curved inner side followed the natural growth rings of the branch. The timber itself was seasoned for two years.

The draw weight of a longbow was between 160-180 pounds, which is hard to accomplish by modern man. In the days of the longbow, in the Middle Ages, men and boys were obliged by law to do target practice with longbows at the village butts every Sunday. The target range for a man was to be no less than 220 yards by order of king Henry VIII.

The longbow was used to devastating effect as long range (400 yards) artillery by the British army at Crecy in 1346 and Agincourt in 1415, raining deadly three ounce, three foot long arrows down on the enemy. As the armies drew closer the longbow could be used accurately to aim at individual targets. Not long after these great victories, which can be attributed to the archers and their longbows, bows were superseded as military weapons by guns.

Flat bows, just as the longbow, can be over six feet long, are not recurved and can be made out of a single length of wood. However, they are rectangular in profile, not ‘D’ shaped.

Short bows are comparable to longbows or flat bows in every detail except size and because they are shorter, they do not have the potential or the distance of the other bows. Sort bows are easy to carry and easier to use in cramped situations like woods or a forest, so they were used by and large for hunting small animals.

Recurve bows are more effective that any other bow inch for inch of length. The tips of a recurve point frontward when the bow is unstrung and look odd to the uninitiated. The recurve was very common from the Mediterranean to the Far East from about 2000 BC until 1700 AD. Nowadays, the recurve is the only type of bow permitted to be used in the Olympic Games.

Compound bows use very stiff materials in their assembly so have pulleys or cams to help bend or draw the bow. This mechanical aid to drawing the bow to the best distance means less physical force on behalf of the archer, which means that the archer con concentrate on the target more.

Crossbows have the limbs mounted crossways on a length of timber and the draw string is held by mechanical means until it is let loose with a trigger. The arrow, or bolt, is much shorter. They are well-nigh half-way houses to firearms.

What Are Chronic Tension Headaches?

There are so many sorts of headache and headaches are so common, that there is a very good chance that everyone you know has had them or still gets them. The reasons why people get headaches are just as wide-ranging. It could be stress, over-medication, migraine, lack of calories or tension. One of the worst kinds is chronic tension headaches.

A normal tension headache feels as if a strap is being done up tightly around your forehead, but they do not have a tendency to last very long and they are few and far between. A chronic tension headache is the same, but it may come every day or even several times a day. A headache is classed as a chronic tension headache if you get a tension headache more than fifteen times in a month for several consecutive months.

Therefore, if you think that you are suffering from this type of headache, start to write notes in a diary. When? Where? How bad? How long it lasted? And anything else that you believe could be relevant, like what you have eaten or drunken that day and the day before. You may become aware of a connection to work or diet.

Some sufferers describe the pain as like having a very tight strap wrapped around their head, others say the feeling of constriction goes down as far as their shoulders. In general, sufferers of tension and chronic tension headaches are in agreement, that the pain is strongest in the forehead, then along the sides of the head and sometimes at the back too.

They say that the typical level of pain is a dull ache which can be mild to moderate in strength. It is more of a nagging, always-on pain than a piercing, distracting pain.

Chronic tension headaches appear to be early risers, that is, some people wake up with them and others say that they begin just after they get up in the morning. It is as if the contemplation of the day ahead is just too much too bear. The pain can get worse at certain times of the day, or it can simply slowly slip away almost unnoticed.

Chronic tension headaches are nowhere near as universal as standard tension headaches, but they are twice as common in women as in men.

The main problem with these headaches, besides the pain itself, is that they become a routine occurrence. You wait for it to happen, you are that certain that it will accompany you throughout the day as before. The pain can just become one permanent drag on your life.

For this reason, sufferers of CTH are often vulnerable to depression and anxiety and it is difficult to know which came first, the CTH or the depression / anxiety and which is causing which. If you think this could be your problem, do not try to cure the headaches yourself, go to see a doctor about the depression or anxiety, have that sorted out and the chronic tension headaches may disappear too without any further medication.

Bow Hunting: Some Aspects

Bow hunting or bowhunting is one of those sports that you either love or you hate – a little like fox hunting in the United Kingdom. Town people hate it and anybody concerned with it and country people see it essential to cull wild animals that could otherwise become a pest.

Despite its macho image, which was encouraged by the film the Deer Hunter, there are growing numbers of women who go bowhunting. The big distinction between hunting with a rifle and hunting with a bow is distance. A hunting rifle with telescopic sights can deliver enough punch at 600 yards to take down a deer with a single shot almost wherever it is hit in the chest.

On the other hand, a hunter using a bow with a fifty pound draw weight will have to be within about forty yards to be able to deliver the same sort of lethal punch, if the shot is accurate to the heart.

This means that if you severely wound an animal from 600 yards, it will most likely be dead by the time you get there, climbing over fallen trees and rocks, but if you severely wound a deer from forty yards you see its anguish.

This has a sobering effect on most bow hunters. The overwhelming majority of bow hunters do not want to see this and they do not want the animal to suffer either, so they wait for the perfect shot. If it is not there, they do not shoot.

A hunting bow has to have a draw weight of at least fifty pounds to hunt large game and that used to mean quite a hefty recurve or longbow, but the compound bow was developed in 1966.

A compound bow makes use of pulleys to assist with the draw, which permits less beefy people to accomplish a draw weight of fifty pounds, which has opened up bowhunting to women and adolescents.

Large wild animals are dangerous and some will attack without warning if they feel threatened. This leads to a danger zone around wild animals. Every sort of animal has a danger zone, for a lion, that could be pretty large and for a deer less so. This danger zone is an locale outside of which you are fairly safe.

If you are hunting with a gun, you can stay outside that danger zone without difficulty, but with a bow and arrow, well, you often have to go within it. This enlarged danger supplies a greater rush for bow hunters – a bigger thrill. Especially if they are hunting bears or mountain lions.

In contrast to the Deer Hunter, most bow hunters go on organized trips these days. The hunting trip is organized with the aid of a specialized firm which will present guided excursions into areas known to have large numbers of the animals you want to hunt.

These expert guides know how to bait areas to lure your prey; they can advise on safety aspects and they carry a big gun in case a hunter is too stupid to take their advice. Regrettably, the gun is to use on the animal, not the idiot.
