Some people have an upset stomach when they drink milk because they are lactose intolerant... that's when the body doesn't make enzymes to digest milk products.

If you have a stomach ache that gets worse after drinking milk, it may be because your body isn't ready to work hard and digest something like milk that has lots of nutrients. Try drinking something more plain like 7-Up or Gatorade until you feel better.

What is more important your Brain, or your Heart???

Now that is a tough question! I would say they are equally important, and depend very much on each other. The brain can't work unless blood is being pumped to it by the heart, and the heart will stop if nerve impulses stop coming to it from the brain.

Of course one could say it is the amazingly capable human brain that sets humans apart from animals. Some animals may have bigger stronger hearts, but no animal has a brain smarter than humans.

There are several types of microscopes. They include simple (one lens) light microscopes, compound (multiple lens) light microscopes, and electron microscopes. You could write a whole book about each of these and its history!

There are so many microscopes being used around the world, I don't think anyone could ever make an accurate count. I'm sure there are many thousands, maybe even millions. I have personally used at least 50 microscopes myself!

Take a look at http://www.howstuffworks.com/light-microscope.htm to learn more.
