A: Dear typical male,
If memory serves, the official counsel is to date only those who "know your standards, respect your standards, and in whose company you can maintain the standards of the Church of Jesus Christ of Latter-day Saints." I'd suggest reading your "For the Strength of Youth" packet better. Remember, they just made a new one.

A: Dear Redbus,
If your forward motion is halted and your forehead hurts, that's a pretty good sign that something is invisible, and it's in your way.
--Benvolio

A: Dear Redbus,
How do you know it's something if you can't see it? What if there really is nothing there?
--agnostic

A: Dear Redbus,
You don't know something is invisible if you can't see it. You can only guess that it is...take that invisible chair right over there...no, no...the one over there, that's right, that one. Now, you don't know it's invisible because you can't see it, but it is invisible, isn't it? Well of course it's invisible! Well look! Can you see it? No. So it must be invisible or else you'd be able to see it, now wouldn't you...honestly, sometimes you are so stubborn. In any case, since you're not willing to just accept simple facts like not being able to see invisible chairs you should probably just forget these kind of questions, because quite frankly, you aren't quite swift enough to get the answers.

A: Dear Very Sweet Kind and Friendly Guy,
Girls don't like you because it is their very nature to be cruel and evil. Let me spell it out for you. When you get into a relationship with a girl, two things swiftly become obvious. The first is girls require a lot of time. The second is that they require a lot of money. These two factors influence each other, so the relationship could be explained this way:

Girls = time x money

Now we must look at those two factors, time and money. We find that time is money, so we make the following adjustment in our calculations:

time = money

Therefore, Girls = money x money OR Girls = money^2 (that's money squared)

We also know that money is the root of all evil, which can be expressed in this manner:

money = evil^(1/2) (That's the square root of evil)

So now we may replace money with ¡Ìevil to produce the following equation:

Girls = (evil^(1/2))^2

This equation is simplified to produce the answer to your question:

Girls = evil

A: Dear sweet guy,
Is that sweet as in "sweet spirit?" If yes, I think we've solved the problem. If no, then there are a myriad of other things that could be wrong. To get them to like you, may I suggest a few tips? Treat them like a princess, but don't condescend. SINCERE compliments, flowers, and expressions of friendship are also appreciated, but remember: everything in moderation. If they think you are a stalker then no one can help you.

A: Dear Whoever,
Resting heart rate is the frequency at which a person's heart beats under normal conditions (that is, not while increasing heart rate through exercise or stress, or lowering heart rate by sleeping). The heart is a muscle whose job is to propel blood throughout the body, and just like any other muscle, the more it gets a work out, the stronger it is and the more efficiently it can do its work. Therefore, the stronger the heart muscle is, the better it can propel blood out to the body. In other words, a stronger heart does not have to beat as often.

So to answer your second question (genetics and certain environmental conditions aside), to lower heart rate for the long term, a person needs to exercise his or her heart and strengthen the muscle, thereby allowing the heart to work more efficiently.

As for your first question, heart rate is most commonly identified by taking one's pulse. Another way to measure the health of a heart is to measure blood pressure--a great indication of how hard one's heart is having to work to propel the blood out.

Here's a set of general guidelines for what one's pulse should be:
(Count beats for minute after having been resting)
Newborns: 100 to 160 beats per minute
1 to 10 years: 70 to 120 beats per minute
Over 10: 60 to 100 beats per minute
Trained athletes: 40 to 60 beats per minute

So your football player was doing alright--definitely on the low end, but likely just due to a good, strong heart.

A: Dear That One Guy,
The short answer is that nobody has done a lot of research in this area, so we don't have one single definite answer. But we do have a bunch of partial answers that may or may not apply to you. We'll see. Just as a preface, the skin under the eyes is very thin, and almost transparent--so it will show any color changes in the layers underneath very easily. Now, onto the possibilities:

First, the blood supply from that skin drains into the internal jugular vein. That drainage is a lot better when you're lying down than when you're standing up so the blood tends to pool there. This is one factor that will give you dark half-circles under the eyes.

Second, you have huge numbers of Mast Cells in the skin under the eyes. These Mast Cells will release histamine (sometimes by themselves, and sometimes when you rub them), which will cause swelling under the eyes-and darkness.

Third, when you get dehydrated (which sometimes happens when you get tired), the skin under the eyes gets dark.

Finally, not so much a reason but a simple observation (after having watched Animal Planet for 2 days straight now): Eyes in animals are an important signaling area, so if we humans get dark under the eyes it's a way of telling other humans that we're tired. Neato, eh?
