Ben
I'm doing an experimental design project for school and my project is about the effects of caffeine on memory, and I need sources about caffeine. I need 2 scholarly journals, and at least one other source. I want the source that is not a scholarly journal to be about the basic information about caffeine. This source cannot be Wikipedia or any similar website. I've looked at WHO's site and FDA's site, but I cannot find basic information about JUST caffeine. Help?
Answer
Caffeine is a bitter, white crystalline xanthine alkaloid that acts as a stimulant drug and an acetylcholinesterase inhibitor.[5][6] Caffeine is found in varying quantities in the seeds, leaves, and fruit of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants. It is most commonly consumed by humans in infusions extracted from the seed of the coffee plant and the leaves of the tea bush, as well as from various foods and drinks containing products derived from the kola nut. Other sources include yerba maté, guarana berries, guayusa, and the yaupon holly.
In humans, caffeine acts as a central nervous system stimulant, temporarily warding off drowsiness and restoring alertness. It is the world's most widely consumed psychoactive drug, but, unlike many other psychoactive substances, it is both legal and unregulated in nearly all parts of the world. Beverages containing caffeine, such as coffee, tea, soft drinks, and energy drinks, enjoy great popularity; in North America, 90% of adults consume caffeine daily.[7]
Caffeine is toxic at sufficiently high doses. Ordinary consumption can have low health risks, even when carried on for years â there may be a modest protective effect against some diseases, including certain types of cancer. Caffeine can have both positive and negative effects on anxiety disorders. Some people experience sleep disruption if they consume caffeine, especially during the evening hours, but others show little disturbance and the effect of caffeine on sleep is highly variable.
Evidence of a risk to pregnancy is equivocal, but some authorities have concluded that prudent advice is for pregnant women to limit consumption to the equivalent of two cups of coffee per day or less.[8] Caffeine has diuretic properties when administered to people who are not used to it, but regular users develop a tolerance to this effect, and studies have generally failed to support the common notion that ordinary consumption contributes significantly to dehydration. With heavy use, strong tolerance develops rapidly and caffeine can produce clinically significant physical and mental dependence.

We are both 16 im turning 17 on the 6th but we want to get married as soon as possible. We are both madly in love with each other and after high school my life is completely planned out. Me and her want to get married is there any way around the parent permission other then pregnancy?
Answer
No, if you're in the U.S., every one of the 50 states requires you to be 18 to marry (a couple the age is 19 and 1 or 2 the age is 21). If you are under 18, you need the consent of a parent (some states require the consent of both parents) unless you are emancipated.

This link gives details on the requirements of each state:

What sort of plan do you have?
How are you going to live? Pay rent, utilities, insurance, car payments, school?
How are you both going to continue your education so that you can both make something of yourself?
No education means = Minimal job opportunities and basically none of them are high paying.
Love is grand, but love doesn't pay for the house, for medicine when the kids get sick, a swing set for the kids, a car payment, it doesn't buy food.
