Improving Your Chances Of Passing Your Driving Test

Anyone who has a driving test coming up will be on the lookout for help and advice because they are bound to be feeling quite nervous about it. It is very stressful leading up to a driving test so the last thing anyone would want would be to fail this test and then have to take it again. But the truth is that failure in this test is very common - at least once. However, you can pass this test on the first attempt and hopefully you will with some help from the following. 

- Always make sure that you arrive at the testing centre a bit early. Being early will mean that you are not going to miss your test, and it will give you a chance to relax and prepare yourself. You could be hampering your chances of success if you end up rushing to get to the centre because this will mean you will be stressed and flustered. 

- Don't look at your driving instructor as someone who is there to fail you, but instead as somebody who is there to pass you. The tester really is looking for reasons to award you with a driving licence. You will perform much better if you have this kind of attitude. 

- Before you arrive at your practical driving test spend time visualising how you are going to perform. This kind of technique is used by thousands of people and many of the top sports professionals say this helps them perform better. Your chances of driving correctly during your test will improve vastly if you have already visualised this. 

- If you want to be feeling alert and fresh on the day of your test then you will have to make sure that the night before the test, you get a good sleep. 

- Do all you can to help yourself feel as relaxed as you can. If it helps then take some deep breaths before you begin your test and don't worry about the tester because he won't give you any marks for doing this. 

Seniors And Driving

Being able to drive is a great asset for seniors who tend to value their freedom and independence as they advance in age. Taking charge of their cars enables seniors to enjoy their freedom and run their lives on their own schedules. They do not have to depend on others for daily errands and are free to pursue healthy social lives. Driving gives seniors self-confidence and assurance.

Therefore, giving up driving is the hardest sacrifice for aging seniors. Much as they like to continue driving forever, weakening health conditions are often the deterrent factor that inhibits one’s ability to drive safely.

Adjusting to life without driving is a difficult experience especially for seniors who have been driving for many years.

Physical Challenges that Hamper Driving Abilities

Different seniors grow old differently; the aging process may depend on a person’s physical condition, illness, family history and lifestyle.

Many seniors may still be fit to be on the road at the age of 75 while others may be encouraged to stop driving when they are 60. A senior’s ability to drive safely can be hampered by the following conditions that are commonly associated with aging.

• Declining visual ability such as poor eyesight, difficulty in gauging the distance of objects on the road and blurred vision can increase one’s safety risk on the road;

• Hearing loss can also cause drivers to ignore honks or voice signals from oncoming traffic;

• Slowing reflexes may result in slow response time when making turns or yielding to pedestrians, bicycles and other cars;

• Increasing forgetfulness among seniors can cause loss of directions or forgetting to turn on headlights at night;

• Weakening muscle strength may lead to inability to make sharp turns or stop the car suddenly when responding to emergency situations;

• The effect of medication such as drowsiness can affect one’s alertness and coordination while driving.

How to Adapt to Life without Driving

Seniors who have been advised by their doctors or family members to stop driving require all the help they can get to adapt to life without driving. They will most likely encounter inconveniences and frustrations associated with the fact that they are not able to be as mobile as before.

The following are possible solutions to help seniors deal with their non-driving lifestyles.

• Community living environments such as retirement communities, assisted living facilities and nursing homes can help seniors adapt to life without driving by providing easy access to daily needs and services such as restaurants or cafeterias, libraries, chapels, grocery stores and fitness centers. Many senior facilities also provide daily shuttle that run on fixed schedules to nearby towns or shops.

• Locating to neighborhoods that are within walking distances to parks, shops and other facilities enables seniors to maintain their freedom and independence while enjoying complete privacy in their own homes.

• Seniors may also engage seniors’ transportation services that offer transportation for seniors to airports, clinics, hospitals or other destinations.

• Other modes of transportation such as bicycles, trains, buses and taxi cabs are also viable options for seniors who want to stay mobile and independent.

Black Walnut Tree Toxicity

Black walnut is a common and useful tree that is native to much ofNorth America .  The natural beauty and hardness of its wood makes black walnut an excellent choice for furniture and woodworking projects.  Unfortunately, black walnut is also the bane of gardeners because of its toxicity to other plants.  

The roots of black walnut trees produce a toxic substance called juglone which adversely affects plants that are sensitive to it.  Plants which cannot tolerate juglone will show symptoms such as yellowing and wilting foliage and they will ultimately die from its toxic effects.  It is believed that juglone acts as a respiration inhibitor, leaving plants unable to breathe and sapping their energy.  

Juglone is produced in the trees’ roots but is present in all parts of black walnut trees, and is strongest in the buds and nut hulls.  The leaves and twigs contain smaller amounts of juglone, but black walnut trees have a habit of continually dropping leaves and nuts from late summer through autumn and this debris only adds to the toxicity problem.  Because of the accumulation of leaves and nuts beneath the tree, and also because of rain running off the leaves, the entire drip zone beneath a black walnut tree can be a hazardous environment for juglone-sensitive plants.  Some plants that are extremely sensitive to juglone won’t grow within fifty feet of the dripzone of a black walnut tree.  

Cutting down the offending black walnut tree won’t solve the juglone problem either.  The roots will continue to release juglone into the soil and the area can remain toxic for several years after the tree is gone.   A gardener I know removed several scruffy black walnut trees from her backyard to make room for a garden, but even six years later she wasn’t able to grow tomatoes in that area.  

The good news is that not all plants are sensitive to juglone.  Many trees, shrubs, flowers and vegetables will grow in close proximity to a black walnut tree, although even some of the juglone-resistant plants will struggle if they are directly beneath the tree.   

Here’s a short list of some of the more popular plants known to tolerate juglone:  

Trees & Shrubs - Eastern redbud, hickories, oaks, most maples, Southern catalpa, red cedar,   peach, cherry, nectarine, some plums and pears, Thuja arborvitae, Euonymous species, and most Viburnums.  

Vegetables - Squash, melons, beets, corn, carrots, onions, parsnips.  

Annual Flowers - Calendula, morning glory, zinnias, fibrous begonias. 

Perennials - Hollyhocks, iris, ferns, most daffodils and narcissus, astilbe, crocus, snowdrops, Jack-in-the-pulpit, cranesbill, coral bells, monarda, spiderwort, some hostas.  

And wouldn’t it just figure;  poison ivy doesn’t mind juglone and will thrive under a black walnut tree.  

Plants which are extremely sensitive to juglone and won’t thrive within fifty feet of the drip line of a black walnut tree include hydrangeas, peonies, rhubarb, silver maple, white birches, apple trees, Norway spruce and Mugo pine, mountain laurels, most azaleas, lilacs, blueberries, cabbage and broccoli, peppers, tomatoes and potatoes.  

Juglone-sensitve plants may be grown in containers that are kept near a black walnut tree, so long as they are not directly beneath the tree where leaves and nuts could fall into the pots or rain could drip from the leaves onto the plants.  

How to Choose the Right Tire

There are a lot of things on your car that need to be regularly checked and replaced, but none may be more important than your tires. As your anchor to the road, your tires need to be in top condition for what ever driving situation you find yourself in. Before you walk into a Marengo tire store, here are a few things you need to keep in mind. 

When purchasing tires, it is important to make sure that all the tires on your car are the same or at least very close to the same. This is most easily done when buying all four tires at once. But lets say you need to change just one or two tires because they were damaged. You just have to makes sure that you try and buy the same brand, size, type, and speed rating. Even if this tire is a little more expensive than others, your safety is worth it. 

The next thing you need to know when buying tires is what kind of conditions you will be driving your car in. Foxlake, IL tires are going to be different than San Diego, CA tires. In Illinois, there is a lot of snow in the winter and lots of rain throughout the spring and summer. Because of this, someone's Foxlake, IL tires are going to need to be the best tire for the worst driving conditions you will face. This might mean buying two sets of tires, one for the summer and one for the winter. This way, you will always have the right tire for your situation. 

For places with milder climates, you may be able to get away with just one, all-season tire. But you have to consider your normal driving habits as well. If your furthest driving distance is to the local shopping center, you can choose just about any tire. If you spend a lot of time in rush hour traffic, you'll be better off getting more responsive tires. For regular long highway trips, you'll need some smooth, quiet, long lasting tires. And it comes to no surprise that you'll want tires with great handling if you frequently find yourself on a winding mountain road. 

One of the last things you need to think about is your tire's speed rating. This is an important number to pay attention to because it can save you money if you know what to look for. Lets say you're at your local Marengo tire store and you think you've picked out the prefect tire. What's the speed rating on that tire? If it is any higher than 150MPH then you're paying too much for a tire that you'll never fully use. When are you ever going to be driving faster than 150MPH? If you knock down your tire's speed rating to 130MPH, you'll also knock down it's price. Most high performance tires come with a higher speed rating, even though you'll never use it, so just know what you're actually paying for. And be cautious. Most tires with a high speed rating have softer rubber and don't last as long. 

Common tire speed ratings: Q= 99 mph S= 112 mph T= 118 mph U= 124 mph H= 130 mph V= up to 149 mph Z= 149 mph and above W= 168 mph Y= 186 mph
