How do placebos help clinical trails?

What are sores that crystalize?

My son has sores that are popping up around his eye and on the inside of his thigh. He also has sores on the inside of his nose that are crystalizing and scabbing over. His nose is congested. He is autistic and prone to multiple disorders, but the doctor keeps putting him back on prednisone and cephalaxin over and over since these have developed and cleared up several times since April. Any ideas?

Is there such a thing as good and evil?

With all the debates about torture and whether it is keeping America safe. and the constant slaughtering of people just to achieve an end of peace..Is there such a thing as good?

The "us versus them" mentality.

1985 Subaru GL doesn't run on 87 octane gasoline?

I am looking into buying a 1985 Subaru GL. I red reviews on this car and it seems very reliable and fuel efficient. The problem I see with the car is it runs on 89 or higher octane gasoline but will not run on 87 octane gasoline. Is this normal for this type of car? It has a 1.8 Litre engine and is carbureted. I cannot find an answer to this question. I want to know if this is normal for this car before I buy it. The owner of the vehicle told me that it only ran on 89 or higher octane.

Anyone want to read my short story? Tell me your opinions. I'm 15.Its called 'simply the truth'?

subject matter and style not bad - If you are serious about writing more, here is my two cents worth of advice: Open your spellchecker settings menu and turn on everything for detection including all grammar and style. Even if you reject some of the suggestions in favour of your style, through repetition of the exercise, you learn a lot about sentence structure, technicalities, etc. But having said all that, for 15 yrs old, it's also pretty decent technically. Well done. I encourage you to do more if it interests you. If you are up to it, maybe you might inspect my work sometime at www.nokilleye.com (see 'Erdman Gallery') and post a comment.
