Central Research Question (This should be in the form of “Is driving a car safer than walking to the city?” – the options and the criterion upon which they’re being judged should be clear.):
What is the best and safest method of birth control?
1. Question (These are the smaller questions that are necessary to be able to answer the larger one, such as “How many people are injured while walking in cities each year?”:
What are the pros and cons from an IDU?
An IUD is a T-shaped plastic device (about 1 1/2 inches long and 1 1/4 inches wide) it contains copper or the hormone progesterone, which your gyno inserts into your uterus to prevent egg implantation. It is 98-99% effective.
Pros-Copper IUD prevents pregnancy for up to 10 years, while progesterone IUD is good for one year; fertility is immediate with removal; IUDs protect against endometrial cancer and possibly cervical cancer. The newly approved IUD called Mirena (which contains progestin) dramatically reduces menstrual bleeding and lasts up to five years.
Cons: No STD protection; spotting may occur between periods; menstrual cramps and flow may increase with copper IUD. Insertion can cause discomfort.
PRICE: About $400 for the IUD and insertion procedure; covered by most insurance plans

2. Question:
How effective are the pills and are they expensive?
The most common pills are combination versions, which prevent ovulation and thicken the cervical mucus so sperm can’t make it into the uterus. But most pills are similar to each other, and many women like the first type they try. Not recommended if you smoke or have an immediate family history of blood clots. Failure rate are 3 percent with perfect use; 8 percent with typical use. Cost $15 to $35 per month.

3. Question:
When choosing any type of birth control what are things women should consider?
When you’re choosing which birth control to use, you have a lot to think about. “Age is one of the first things to consider, you also need to factor in your menstrual and medical histories, convenience, and cost. You could be looking to prevent pregnancy now but planning to conceive in the distant future. You might already have babies on the brain. Or you may be in between. In other words, you need contraception with some flexibility.

4. Question:

Older adults who drink coffee—whether caffeinated or decaffeinated—have a lower risk of death from heart disease, respiratory disease, stroke, injuries and accidents, diabetes and infections than older adults who don’t drink coffee, according to a study published in the May 17, 2012, issue of the New England Journal of Medicine.

5. Question:
Is antioxidants a good source from coffee?
It’s estimated that coffee is the main source of antioxidants in the American diet. A 2006 study of postmenopausal women concluded that because of caffeine’s antioxidant properties, coffee may inhibit inflammation linked to heart disease and other inflammatory diseases. So overall no antioxidants are not good however as long as we eat a well balanced food intake then the antioxidants from coffee should be ok.

6. Question:
If Caffeinated Coffee helps one live longer, will decaf coffee have the same effect?
We have attributed the cardiovascular effects of coffee to caffeine but we found non-coffee drinkers given decaffeinated coffee also display the same effects.

7. Question:
Where was this study taken place in and in what ways did it show people who drink coffee live longer?
The study was done by the National Institutes of Health and AARP. this doesn’t prove that coffee makes people live longer, only that the two seem related. Like most studies on diet and health, this one was based strictly on observing people’s habits and resulting health. So it can’t prove cause and effect.

8. Question:
Overall is coffee good for our body?
Coffee is known to be a good dietary source of antioxidants and the health benefits of these substances are broad. They are believed to protect the human body from such conditions as premature aging, cardiovascular disease, certain cancers and degenerative brain diseases. Scientific studies are indicating that there is a link between drinking coffee and the prevention of Parkinson’s disease,( n1) Alzheimer’s disease,( n2) type II diabetes,( n3) colon and liver cancer.( n4, n5) The good news is, research indicates that coffee contains higher levels of antioxidants than green tea, cocoa, herbal teas and red wine( n6).

10. Question:
How many cups of coffee are recommended on daily intake?
Research has yet to find that caffeine is harmful when consumed in moderate quantities:
400 mg per day or less. To put that into perspective, one 8 oz (237 mL) cup of coffee can
contain between 75 and 180 mg of caffeine.

11. Question:
What can coffee do to our body?
There is evidence that caffeine has the potential to improve cognitive functions that are timed such as reaction time, decision-making, or cancellation tasks. Its influence on mood depends on the amount of caffeine consumed, individual differences, and arousal states. In real-life simulations, caffeine appears to improve performance of artificial tasks and simulations of driving and industrial work.

12. Question:
How can we prove that this study is true?
Although this study cannot draw a cause and effect link between coffee and longevity, it strongly suggests there is no harm in it.

13. Question:
Does coffee benefits differ in genders?
In fully adjusted models using either standard or IRT 3MS scores, we found modestly reduced rates of cognitive decline for some, but not all, levels of coffee and tea consumption for women, with no consistent effect for men. Caffeine consumption was also associated with attenuation in cognitive decline in women. Dose- response relationships were not linear. These longitudinal analyses suggest a somewhat attenuated rate of cognitive decline among tea and coffee consumers compared to non-consumers in women but not in men.

14. Question:
Does coffee affect our blood pressure?
The effects of caffeine appear to be more pronounced in persons who are at risk for hypertension, such as individuals with a family history of hypertension or obesity.4 Although there is often less or no effect of caffeine on BP in habitual coffee drinkers, this is not always true; some people do not develop a tolerance to the BP effects of caffeine.5
