" ... 1.) Atmospheric drag. This is by far the biggest effect, and this is the reason that low-Earth orbits are so unstable. Other satellites -- like geosynchronous satellites -- will decay as well, but not on such short timescales. We normally define "space" as being anything more than 100 kilometers (62 miles) up: the Kármán Line. But any definition like this, of where space begins and a planet's atmosphere ends, is truly artificial. In reality, atmospheric particles continue to extend arbitrarily far to high altitudes, just with the density becoming less and less the farther away you move. Eventually, the density drops so low -- below a microgram per cubic centimeter, or a nanogram, or a picogram -- that you say "we're effectively in space." But atoms persist from the atmosphere for thousands of kilometers (or miles), and when a satellite collides with those atoms, they lose momentum and slow down. This is why low-Earth orbit satellites are so unstable. ... "
" ... Research has shown that the amount of egg protein in a dose of influenza vaccine is less than 1 microgram. A microgram is one-millionth of a gram, or, if you’re not into the metric system, 28,349,523.125 micrograms equal one ounce. In other words, the amount of egg protein in a dose of influenza vaccine is so teeny that, as the allergists say in their practice parameter, “it’s highly unlikely to cause reactions even in the most severely egg allergic recipients.” ...

" ... Up until now, the only resource available to women has been standardized tests that repeatedly fail women because they cover a broad range that is of little help when trying to diagnose the effects of a microgram difference in hormones that may mean a huge impact for one woman and very little for another. These tests are further complicated by the fact that our hormones fluctuate by the hour and time of day. One of the most common frustrations expressed by doctors is that a blood test can only give a snapshot of one moment in time in a woman’s body, making it almost impossible to determine what her true hormone needs are. Hormones are probably one of the least understood systems in the human body and most difficult to gauge and address despite having the biggest impact on not just our health, but our personality, will and drive. That’s because hormones are made by multiple organs in the body and they all impact each other, which means, give too much or too little and the whole system can go into chaos causing symptoms from fatigue to weight gain, mood swings, heart attacks, loss of sex drive and vaginismus. Just how many organs contribute to hormone production? The thyroid, pituitary, pineal, hypothalamus, liver, ovaries, adrenals and those are the main ones. Out of frustration, many women have turned to saliva kits in the past despite differences of opinion in the medical world as to their accuracy and efficacy. Mira offers hope to solve this problem. ... "
