If you have ever watched the Discovery Channel, you know animals are amazing. Giraffes, for example, have a few weeks after they are born and they develop full fledged adults so that they can survive. Humans are animals too, and we run on the same program as our other mammal cousins.

With that in mind, the recent debate over human growth hormone that has come to light is very interesting. On one hand it is a chemical the body produces naturally, on the other it is also a huge performance enhancer. Should human growth hormone be legal? Why should it be illegal? These are the questions driving the debate right now, and there are many heated arguments from both sides.

My personal opinion is that human growth hormone is produced in your body at a rate determined by your genes and that's that. Putting stuff in there that doesn't belong is cheating nature - even though the substance is natural. Marijuana and alcohol are natural, but should people take it to be happy when they are depressed? I don't think so.

The same with human growth hormone - what's in the body should stay there. Don't mess with nature.
