The Truth About Caffeine
How many of you here consider yourself caffeine addicts? How much coffee do you drink in a day? One cup? Two cups? More? How about caffeinated sodas?
Caffeine is pervasive in our society these days and every few months we hear about how a study has shown that it is bad for us or good for us. What are we to believe?
Today, I'd like to give you some of the facts about caffeine and its effects on your body. I may not cause you to change your coffee consumption, but at least you'll be better informed about what you are putting into your body.
I'm going to talk about the beneficial effects of caffeine, the negative effects and discuss what are considered to be 'safe' levels of caffeine consumption.
Let's start with the good news. Caffeine, which comes from the leaves, seeds and fruits of about 63 different plants, is well known as a stimulant. That's why people drink it, right?
Caffeine does help you wake up and feel more alert and it has been shown to increase attention spans. This is a beneficial effect for people who are driving long distances and for people who are doing tedious work. Calling this a health benefit may be stretching it, though staying awake while you are driving a car definitely contributes to your well-being!
Caffeine also contains antioxidants, which have been shown to have cancer prevention qualities.
The negative effects of caffeine are largely dependent on how much you consume.
When consumed in small quantities - for example, when you have one cup of coffee or one soda - caffeine can increase your heart rate, cause you to urinate more (which can cause dehydration) and prompt your digestive system to produce more acid.
In larger amounts, caffeine can cause you to have headaches, feel restless and nervous, be unable to sleep, and even - in very large quantities - to have hallucinations. (Don't try that at home!)
When larger amounts of caffeine (over 600 mg per day) are ingested over long periods of time, they can cause sleep problems, depression and digestion issues.
According to a Medline article on the National Institutes of Health website, having caffeine in your diet is not of any benefit to your health, but by the same token moderate consumption is not considered harmful.
They say that having up to 3 eight ounce cups of coffee a day - or 250 mg of caffeine - is considered (quote) "average or moderate". 10 cups of coffee a day is considered excessive. Also, remember that the amount of caffeine per cup can vary greatly depending on the type of beans that are used and the strength of the brew.
Most sodas with caffeine, unless they are specially enhanced, have about 35 mg of caffeine per 8 ounces. This means that you don't have to worry TOO much unless you are drinking several 2 liter bottles per day. Also, the effect of caffeine on you personally will depend on a number of factors, such as your weight, general health, mood and personal sensitivity to caffeine.
As you can see, caffeine can have both positive and negative effects on our health and well-being. Nevertheless, the bottom line is that if you drink your coffee or sodas in moderation, you don't have to worry too much.
So, the next time you are wondering whether or not you should have that second cup of coffee to perk you up, relax. At least now you know what it will - and won't - do for you!

Speech Goal: I would like to give everybody an insight on Tiger Wood’s life. I will talk about his early childhood, golf career, and the scandal that became his downfall.
Who in your opinion is the most dominant well-known figure in professional sports? This is up for debate to many of us as we all have different likes or interests. But there is one individual who was destined for stardom and was in the spotlight at a very early age.
He is arguably the one individual in our lifetime that transformed his sport. With his presence, the sport of golf became popular and was no longer a ratings buster on television, and became a sport more young kids wanted to get involved in.…show more content…
B. His dad saw that he had an interest in golf at a very early age and designated him as “The Chosen One” (Callahan 23). 1. When Tiger was a toddler, his dad would put him in his high chair while he would hit golf balls in the basement. He noticed Tiger watching every move he made. Soon enough, Tiger was mimicking his dad’s golf swing and Earl Woods became amazed at what Tiger could do with a golf club by the age of 2. 2. Tiger became noticed by the world at the ripe old age of two yrs. old when he appeared on the Mike Douglas show.

He had a close relationship with his father and it is well documented that Tiger got his mental toughness through him. His dad use makes all kinds of noises while Tiger would attempt to practice.
