The following diagram displays the increased relative risk (or "odds ratio") that is associated with some of the more well-researched environmental factors (family history/genetics is included for comparison) that have been linked with schizophrenia. In this diagram, the "odds ratio" represents the relative increase in risk associated with schizophrenia, where a "1" is average. So, a child born during the winter months (January through March/April, in the Northern hemisphere) has about a 10% higher risk of schizophrenia than average. A person born in an urban environment has about a 50% (with an odds ratio of ) higher risk of developing schizophrenia. A child born from a mother who has Rubella has about a 500% increased risk of schizophrenia, etc. The "family history" odds ratio identified below is actually much more difficult to estimate than the number below suggests - it depends upon (as mentioned in the genetic factors above) the level of interelatedness of the family member who had schizophrenia, and other brain disorders in the family. To get an accurate reading on this for any individual it is best to talk with a genetic counselor .
Coming home from a long day at work, you take a seat in your favorite chair and turn on your stereo. Suddenly, life seems more manageable, and it may just have a little something to do with your favorite music pleasurably bombarding you from all directions. A home audio system is important: your home is your personal space, and everyone's personal space needs the right music to set the right mood. Whether you're hooking up the best stereo system available to play your music as it was meant to be heard, or attaching the right components to create a surround-sound system to go for that immersive movie experience, finding the right home audio equipment is an important undertaking.
Casting an evil spell is an evil act, but for most characters simply casting such a spell once isn’t enough to change her alignment ; this only occurs if the spell is used for a truly abhorrent act, or if the caster established a pattern of casting evil spells over a long period. A wizard who uses animate dead to create guardians for defenseless people won’t turn evil , but he will if he does it over and over again. The GM decides whether the character’s alignment changes, but typically casting two evil spells is enough to turn a good creature nongood, and three or more evils spells move the caster from nongood to evil. The greater the amount of time between castings, the less likely alignment will change. Some spells require sacrificing a sentient creature, a major evil act that makes the caster evil in almost every circumstance.
