Do you think that my poem is pable? PLEASE THIS IS QUITE IMPORTANT TO ME?

Most of this is irrelevant phrases stuck together like so much overcooked rice. Just kinda clumps and sticks to the spoon. It is hard for me to see this as poetry of any kind, and to my mind, it is not pable or palatable.

What if hitler had never been born?

Would there had been a second world war? Would it have kept the same, with hitler replace with another person from the nazi party, and WWII have gone on like normal? Would russia's push for world revolution upset the 'free' countrys to a point where WWII was brought about as a, "NATO VS COMMUNIST" war? Would there have been peace? There woulden't have been a korea or vietnam war, seeing as the communism in north korea and vietnam where caused by the land-split at the end of WWII.... what do you think?

A medical question. Female immune system.?

Women live longer than men. In making babies they share their immunity with the young. When ill, women recover faster, and continue to work through illnesses that would incapacitate a male. There could be some justification to their saying that it's because "they have to." My Q is: do women have a better immune system than men? The evidence would suggest that this is so.

Why did WWE take Matt Striker off of announcing Smackdown? Do you think he will ever return?

When Matt Striker first came as an announcer, I thought he was great, not JR great, but still great. From then on, he proved time and time again that he is a better announcer than anyone else WWE currently has. Then in December it was being reported that both The King and Cole were trying to get Stiker off PPV commentary. Personally, I think they both jealous cause Striker is a better announcer than both of them. Anyways, the next PPV came, and he still announced, only until the main event where CM Punk replaced him. As we all know, Punk left announcing to start a feud with Cena, and Striker was back full time at the Royal Rumble. But the following Smackdown, he was replaced by Booker T. This makes no sense to me, because if they were going to replace anybody, it should have been Cole. Personal feelings aside, cause I cant stand the guy, he is already on Raw. What was the point of keeping him on both shows. They should have had Cole leave Smackdown. Now, we are stuck with an excuse of an announce team on Raw, I call them that cause all they do is bicker all night. And an announce team on Smackdown where, Matthews and Cole bicker all night, and Booker tries to announce. Basically, my question is: What is going to happen to Striker, and do you think he will ever return to announcing?

3 simple steps to get wwe back to greatness !!?

I agree with the first two, especially the first but not really the third. Scraping PG would be great and all but if you need over the top violence two make great wrestling then you have a problem ( not you personally but the talent in WWE). Some violence is great when done right, but when it is forced even that can get boring. Just look at Hell in a Cell and Elimination Chamber matches today. I loved the attitude era, but there is a reason to why it ended.
