[texhax] It's good to exercise

See my book on p-adic numbers. I didn't follow the convention of putting 
exercises at the end. It depends on what you're trying to do, but it 
worked for what I was aiming for in that book.

The theorem package would allow you to set up a separate numbering 
scheme for exercises, but (as you'll see in my book) I ended up creating 
my own macro for exercises, and just numbered them sequentially 
throughout the book.

Religion, opium for the people. To those suffering pain, humiliation, 
illness, and serfdom, it promised a reward in an afterlife. And now we 
are witnessing a transformation. A true opium for the people is a belief 
in nothingness after death---the huge solace of thinking that for our 
betrayals, greed, cowardice, murder we are not going to be judged.
