All of us have heard about genealogy tracking, but do you think we can really track our historical ancestors with these tests? The answer is no. Everyone around the world is in a craze to know from which historical figure they have ascended. Using this craze, many companies are doing big business with genealogy tracking by promising their customers that they will perform a DNA ancestry test, which will cost around $300.

Nothing but a possible interpretation
Some scientists around the world have raised awareness regarding these DNA ancestry tests and called them genetic astrology as they are entirely flawed and can never be relied upon. Companies promise to make new discoveries regarding your ancestors and your cultural roots and demand a lump amount of money for that. It is scientifically proven that the DNA that we inherit from our relatives just a few generations back are nothing compared to the huge amount of DNA that we have shared with our common ancestors. So performing these DNA ancestry tests will give us results that are just one possible interpretation among many more.

Though it may sound exciting, it is not a reliable truth

Humans, throughout history, have migrated from one place to another. Who knows whether your ancestor even lived in the same country as you are? Because of this, there may be a thousand possibilities regarding your genealogy. You can never rely on any service centers who provide these DNA ancestry tests and predict that you have ascended from an eminent historical character. It is good to hear, but may not be the truth.

The DNA for any individual is compared with the DNA of that person about whom some information regarding ethnicity is already present, and some of the aspects of the DNA are looked into.

Some of these are
The DNA of the Y chromosome is only found in men as it ascends along the male line.
The DNA of the mitochondria is present in both males and females as it is inherited by both. There is only one ancestral lineage for an individual regarding the mitochondrial DNA.
Autosomal DNA makes about 98% of your DNA and it can be inherited from any of your ancestors. It is made up of numerous sections of DNA, and each section has its own history to tell.

The one thing that is clear from all this is that the more you go back in your generations, the more amount of DNA you will share and the DNA ancestry tests will become vaguer as you go up the ladder of your ancestors. If any DNA ancestry test concludes that your DNA has matched with a certain person belonging to a totally different community in some other part of the world, the only chance is that maybe some of your ancestors, long before, were in that community. DNA ancestry tests are accurate when you want to know your family maybe up to two to three generations, but as you go back there is a vast mix of genetic material, and the results are increasingly unreliable.

The decision to buy the best mattresses depends on a lot of factors, but the weight of the sleeper is probably one of the most important, yet underrated consideration. It might not seem important, but this factor matters and should weigh in heavily when picking a mattress. The support provided by a mattress, its sinkage, plushness, cooling mechanism and overall feel can be majorly influenced by the body type as well as the body weight. To create the ideal feeling and support required by the body, every mattress needs to be configured for the body weight and type it will be supporting. The best mattresses to buy can depend on the weight of the sleeper and can be classified into the following categories:

Medium feel for people weighing 150 pounds or less
People who weigh less than 150 pounds do not tend to sink too deep into their mattresses, which means that the top layers of the mattress that are too dense may not feel too comfortable with them. Choosing a mattress a few points lower than the recommended point is essential because most mattresses are designed for average sleepers.

Medium feel for people weighing between 150 – 200 pounds
People weighing between 150-200 pounds are considered to be average sleepers, the sweet spot for the marketers since most mattresses are designed around this weight range. The universal comfort range of mattresses falls on 5-7 on a scale of ten, and these are characterized as a medium, medium firm and luxury firm.

Medium feel for people weighing between 200 pounds and more
People who weigh 200 pounds or more are classified under the heavy sleepers range, and a mattress needs to account for the extra weight and pressure that is received through these sleepers. A comfort layer of at least 4 inches is required, and it provides consistent comfort and support for heavy sleepers. Some people who have extra cooling needs or require a mattress that provides extra edge support often opt for coil on coil mattresses or luxury innerspring options. A mattress that focuses on the foam side rather than edger support offers more body shaping and contouring options.

Soft feel for light sleepers
Since light sleepers do not sink into a mattress that has a foam base, certain mattresses work very well for them. Foam mattresses offer the plush, cloud-like sensation without bending down under the weight to cause support and heat retention issues. A range of 3-4 in terms of the firmness scale out of 10 are for this class of sleepers.

Soft feel for average sleepers
Average sleepers who need a soft feel are akin to the light sleepers of the same category. Anybody near the 150-pound weight mark can proceed to follow the same instructions as those for light sleepers, while those nearing the 200-pound weight mark would need to consider the sinkage aspect of the mattress. While side sleepers prefer an increased level of sinkage, most back and almost all stomach sleepers do not like it and prefer a firmer support.

Soft feel for heavy sleepers
Heavy sleepers who weigh over 200 pounds and more and need a soft feel often find it difficult to find a mattress that works well for them in terms of both comfort and support. A mattress that offers deep compression support is the need for these cases.

Different body types require different mattress types and best mattresses to buy depend on these factors.

Vehicle navigation is one application of all the aspects of GPS Systems that the common man uses the most. With the advent of smartphones which are GPS-incorporated, car navigation has become immensely popular. However, it has introduced a limitation that an internet or a mobile service is necessary for its operation. These navigation systems are equipped with various other facilities that has made driving safer and more relaxed activity. This write up tries to explain the intricacies of the system in jargon free language. There are various devices in the market with many added features.

The navigation device has the following elements.

The GPS antenna receiver receives the signals from the satellite.
The direction sensor provides the direction in which the vehicle is travelling.
The speed sensor provides the speed of the vehicle and the system calculates the distance has yet to travel to reach the destination.
The display screen to show the navigation computer output.
The Map data base checks the information from the antenna and sensors against the map database and sends the outputs to the display screen using the control circuitry of the navigation computer.
Navigation computer, which is the brain of the system. It compares the information received from the antenna, the various onboard sensors and compares them with the map database and determines the vehicle’s exact present position, and calculates the time of possible arrival at destination, taking into consideration the remaining distance, vehicle speed etc. It shows the remaining distance to the distance also.

Another important function the navigator is to perform is route selection and constantly monitor traffic on this and other parallel routes to avoid traffic congestion and resulting delays.
These functions it performs by using the four following databases.

Road Network data, road configuration, connection conditions, attributes etc.
Background data which gives information like rivers, shorelines, railroads, contours etc.
Site information data such as building names, addresses, representative structures etc.

Voice data voice guidance: Firstly, the current location is determined consulting current location details. Secondly, it finds the destination and setting using the destination details. Third, the route to the destination is searched and fixed. Lastly, it searches for a route which is shortest and quickest, and recommends the same to the driver.

Background data are searched to provide guidance using the voice guidance.
Route details are displayed.

Finally, it collates information received from various agencies like traffic police other drivers and informs of traffic congestions. All in all, it makes driving to any destination hassle free and smooth.

A counselor provides therapy to addicts enrolled in drugs and alcohol rehab centers. Their function is to find the root cause of the addiction and help the addict move on to a sober life. The counselor develops a therapy and recovery plan for each individual enrolled in drugs and alcohol rehab centers. They have to educate the addict about their addiction and what it is doing to them and how to move to a life without abuse. All this has to be achieved through counseling.

Why is counseling important for addicts
Addiction is more than just a physical dependence on drugs or alcohol. Even post the detoxification process, there are high chances of addicts relapsing. Factors which contribute to relapse include social media, environmental cues (for example, visiting a drug-frequented neighborhood), or even stress. Hence, counseling is important for the addict to not relapse.

Types of therapy
Not all individuals enrolled in drugs and alcohol rehab centers would respond to the same type of treatment; hence, several types of therapy need to be formulated as per the need of the individual. Some popular therapy types include motivational interviewing, contingency management, cognitive behavioral therapy, family therapy, and so on.

• Motivational interviewing: This type of therapy tries to prepare an individual to change his behavior and accept treatment for the addictions. The patient has to accept his behavior and make changes where required. The user has to realize that change has to come from them if they wish to start living a sober life.
• Contingency management: This type of therapy is positive reinforcement counseling. It encourages the patient to abstain from drug use. The patient is rewarded for progress. This form of therapy is very successful and highly effective in drug abuse cases.
• Cognitive-behavioral therapy: One of the most common types of therapies, it helps patients understand the situations that can lead them to use drugs. It also teaches them coping skills. He/she recognizes negative thoughts, triggers, emotions, and devices. This skill, once learned, remains with the patient for a long time.
• Family therapy: This type of therapy is multidimensional as it addresses the influence that a family has on the patient. They work with each family member alone and then as a unit. This treatment is sought for young patients.

A drug abuse counselor requires qualities like compassion, patience, understanding, and sensitivity. Counselors put a great deal of time, energy, and hope in understanding and helping their patients.

Hypertension or high blood pressure is a medical condition where the blood pressure of the individual exceeds the normal blood pressure range. Hypertension affects millions across the globe. This condition does not affect adults alone, as teens and children are also affected by high blood pressure. Hypertension symptoms are difficult to spot and usually appear only at critical stages. The only way to detect hypertension is to check your blood pressure regularly.

Normal blood pressure is 120/80 mmHg. Blood pressure above this range is considered high blood pressure. Unchecked hypertension increases your risk of other serious health issues. Hypertension is a condition that develops over the years

Causes of hypertension
Hypertension is a chronic condition that is categorized into primary and secondary hypertension. A common type of hypertension is primary hypertension. This type of hypertension does not have any particular cause but develops over a period of time. Secondary hypertension is the result of a separate health condition. A highly stressful or lethargic lifestyle is a precursor for hypertension. Alcohol consumption and smoking habits are also known to cause heart-related issues in the long run.

Symptoms of hypertension
Hypertension symptoms are often mistaken for those of other diseases. Signs and symptoms of hypertension are not specific and usually occur only at severe and life-threatening stages. Common hypertension symptoms are as follows:

• A severe headache: A severe migraine headache is a classic symptom of hypertension.
• Fatigue or confusion: People with high blood pressure experience fatigue or are in a confused state of mind.
• Anxiety: People with high blood pressure are often anxiety ridden. However, this symptom may be due to other health issues as well.
• Vision problems: Chronic hypertension results in damage to blood vessels in the eyes.
• Irregular heartbeat: Irregular heartbeat is a symptom related to all cardiac diseases.
• Shortness of breath, chest pain, blood in urine, and pounding in the ears, chest or neck are other common symptoms of hypertension.
• Hypertension symptoms like dizzy spells, nosebleeds or dull headaches are rare but warrant emergency medical help. These symptoms of hypertension occur during blood pressure spikes (180/120 mmHg) and termed as a hypertensive crisis.

Hypertension symptoms are very subtle; you may not even know that you have it. Hypertension is a “silent killer” since it is a largely symptomless condition. Regularly check your blood pressure if you have a family history of cardiac issues or any other symptoms.

All of us have experienced a drop in our finances. We think of various ways to get out of the situation, but we hit a snag. This is when many people turn to the best balance transfer, which will help them to lower their credit card debt. In case you are stuck in such a situation, don’t panic. Listed below are some of the options available to you:

• There is nothing like being able to get a balance transfer at this time in order to lower your credit card debt. Paying interest on debts is what puts you in even deeper debt. Best balance transfer cards can help you as most of them come with 0% interest payments for the promotion period. But make sure that you are aware of the balance transfer fee that banks charge you as they may sometimes work out more in favor of the bank than in favor of you. To qualify for the best balance transfer you would need an excellent or good credit, only then can you be eligible to obtain a 0% card. That is a big hurdle that you need to jump over in order to get debt free. The next hurdle would be to get a high credit line on the 0% card to transfer your entire high-interest balance to it.
• You need to make sure that by doing a balance transfer your whole debt and not just a portion of it is refinanced. If this happens, you need to call the issuer of the best balance transfer and ask them for a higher credit limit. Some of them may be a little flexible, and you might just get what you wish.
• If talking to an issuer doesn’t help, then you should try and apply for a personal loan.

Hence, getting a balance transfer with a low credit limit is not impossible.
