3 Problems?!?!?!?

I have two problems that I seem that i cannot fix at all.

The first one is that every time I hover my mouse over some link on my website, the text just turns small for some reason instead of staying the same size as it would usually do in any other website.

The second is that I have a couple of pages on my site but whenever i try to post and try to only make it viewable in one page, it just doesnt work.

Third is that at the bottom of the footer i have the copyright but right next to it there is a link to some pharmacy that I never put and i dont know how to take off..

Can anyone help me???? http://www.bodyweightphysique.com
