I'm a Scorpio, but I don't really think I act like one at all except for the fact that I can be very secretive.

I don't believe in astrology though.

What about you?

I'm studying about ecosystem, and it seems as if everything that an organism does if just for one purpose which is to reproduce... My Biology book says that the reason why anyone would save anyone is so that the people can reproduce -_-.................. so that their species won't run out. and the reason why people would take risk to save someone else is so that that person may reproduce (my biology book also says that a person is more likely to save a relative than a friend because relatives share similar DNA as them and that saving them would help spread more similar DNA and they call this "altruism" ).........

There is a new alarm called the "Mosquito" alarm system, that constantly blairs an extreamly high-pitched squeal. So high pitched, in fact, that you have to be a teen-ager to hear it. As the human ear ages, certian cells in it die. Hearing deterioates over age, we all know that. But a group of scientists recently discovered the frequency of 15Khz, a sound only audible to persons under the age of 30, or occationaly 18. This sound cannot be heard by adults, but causes great irritation and sometimes pain among those who can hear it, namely teenagers. Using this new frequncy, alarms were built and instaled in various shops and stores over England, repelling teenagers "guilty" of loitering.

So my question is this: is it ethic to be treating todays teenagers the same way we treat dogs with a dog whistle? To blare constantly a head-splitting noise that can only affect a certian group, while adults are so oblivious to the noise? Or is it better to prevent "loitering?" What do you think?
