weight bearing exercise ( as bones grow on stress lines) and adequate Vitamin C intake (with adequate vitamin D, as Vitamin C requires Vitamin D to be absorbed).
There are a number of ways to prevent body odor. These ways are like: 1)Shower once or twice a day, especially after practice. 2)Use deodorant daily to prevent sweat after odor 3)Take a lot of water for effective respiration. 4)Do not repeat clothes and wash clothes after you have already worn them.
First off, let me just start off by saying "more effective" doesn't mean "safer". Anyways, most agree that direct passages to the blood stream are the most effective ways to get high. This way, your body doesn't filter as much of the substance if you were to say eat the drug. Insufflation (snorting), rectal absorbtion, and injection are three ways drug users get more "bang for their buck".
That's a really good question. As of today, there are no effective ways known to reduce the number of serial killers. Partially due to the fact that it is not entirely understood what makes these kinds of killers. Research into the problem continues and hopefully someday there will be better understanding and an effective way to prevent serial murder.
