A matter of great debate in the car and driver world is one that has no real promise of beings resolved: whether it is better to drive manual or stick shift or whether an automatic transmission is better. As I see it, it’s a simple case of having to weigh the pros and the cons.
Automatic transmissions clearly have the advantage of being convenient. You simply turn on the car, put it into gear, and you’re off - you never once have to worry about shifting a stick, stepping on a clutch pedal, stalling, or any of that. That’s a huge convenience, especially given how hectic the roads can get these days. But with an automatic transmission you lose a few features.
First, you lose the ability to downshift as you can in stick shift, which can give you the speed you need to pass someone or else slow you down quickly without having to apply the brake. Second, because you can’t downshift and because the high gears of automatic transmissions tend be a little tighter than the high gears of manual transmissions, gas is burned faster in two ways. Because slowing down in a car with an automatic transmission requires the brakes, re-accelerating without momentum will burn more gas; and because the high gears tend to be tighter in an automatic, the engine will work harder at higher speeds to maintain speed.
Manual definitely has the disadvantage of being annoying to drive. The co-ordination of a clutch pedal and a stick to shift is more than a hassle and is actually probably a little bit less safe since the shift requires a hand that could otherwise be used controlling the wheel.
But what manual lacks in convenience it makes up for in control. Being able to downshift enables the driver to accelerate and slow more quickly than an automatic transmission will allow, and more predictably since the driver is controlling the action; being able to shift into looser high gears also makes it easier to conserve gas on the highway without overworking the engine.
But why choose if you don’t have to? Semiautomatic transmissions offer the best of both worlds; automatic shifting with the ability to downshift and shift up as necessary.

My computer started to run poorly several years after I had originally purchased it. I was worried that one day it would just stop working entirely. I worked from home and I relied upon my computer every day. I ran a small business on-line reselling items that I picked up at rummage sales and re-sale shops for a profit. I used my computer to check bids on-line, to communicate with buyers, and to advertise. I also used several of its programs for keeping track of my invoices, my expenditures, and to keep track of photos that I took of the items I was selling. I had owned the Dell computer for several years and had just noticed recently that its overall performance was declining.
I had someone tell me that my computer may be running poorly because it could be running low on memory. I had suspected that this was possible, but did not think that it was likely. I was also unaware of how I would be able to diagnose my computer’s problem without professional assistance. I called out a local computer repairman to come and take a look at it. After a series of tests the repairman informed me that my computer was very low on memory. I guess all of the photo files containing pictures of my merchandise had taken up a large amount of memory. Somehow I had taken the continued performance of my computer for granted, expecting it to work forever. I really didn’t realize that photos used up so much memory either.
I could not afford a new computer so I decided to look into Dell memory upgrades. I was concerned that these upgrades would be expensive and that I would be spending the same amount of money on the technician and memory upgrade that I could be spending on an entire brand new computer. Luckily, the Dell memory upgrades were much more affordable than I had though they would be.
The computer technician came back to my house and installed my Dell memory upgrades in less than twenty minutes. The process was actually quite simple and a lot cheaper than I thought it would be. I ended up saving myself hundreds of dollars by not running out and just buying an entire new computer. My computer was up and running like new and now I could add a thousand more pictures of items for sale.

The history of America’s armed forces is uncompromised, proven by a valor to serve and fight for our most cherished freedoms. When you wear a formal army uniform, you are donning your best and your brightest in order to represent the elite fighting force you belong to. Whether visiting senior citizen centers, attending Mass, or speaking to a group of Boy Scouts, you wear your uniform for formal occasions as a symbol of America’s bravery in the face of tyranny.
Your uniform should have a dignified look, adorned with a selection of US Army medals that not only adds color and texture, but a feeling of dignity and respect as well. Success is in the details, signified through the varied colors of ribbons and medals that instill the sense of dignity to the uniform. When you proudly display your US Army medals, you display your gratitude to serve, your pride in representing an elite fighting force protecting this country’s sacred freedoms.
Pins in a medal vary according to where you prefer to display it. Long pins are ideal for a service coat, while shorter pins can be pinned to a shirt. Any pin, however, will cause fraying and deterioration over time, so a magnetic backing is best, attaching to the shirt without damaging the fabric.
While original military ribbons are generally heavy, ¾ of an inch thick, they were designed for display primarily on a display rack or other decorative case. As more soldiers chose to proudly display their ribbons on their formal dress uniforms, on-line companies now offer ribbons only 1/8 of an inch thick that could be applied to the fabric without weighing it down. They have the same dignified colors as the original medals, without the heavy weight that unnaturally sag a shirt.
On-line companies offer a wide selection of military medals that are sure to add dignity to any uniform. A medal is more than a sign of respect. It’s a tribute to the greater legacy of the American military, a bond that exists between soldiers who carry on the mission of defending freedom to this very day. No matter the theater, American service men and women will answer the call to defend the world from the evils of tyranny.
