Yes you can certainly click on ads on other hubs. The adsense publisher id for those hubs is different from yours and does not affect your adsense account. All this information is saved in cookies in your browser and that is how Google can track if the same user who owns the ads is clicking on their own ads.
Yes of course, that's how hubbers earn some extra cents ;)And Google is also happy if someone is interested in their ads and clicks them ;).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
