Minecraft is a very amazing game that allows you to do lots of different things. Some shouldn't be tried. :) Here's a list of things you should not attempt in Minecraft.

1. Skydiving from at a really high tower and trying to land in one block of water :)

2. Trying to jump over a lava pool. (Usually results in a painful death where you lose diamonds. Never a good thing.)

3. Lighting the forest on fire. Mother nature will never forgive you.

4. Hitting a pack of wolves. Be careful, they have been tested and have been proven to have have rabies. Probably doesn't matter because you'll gonna die anyway. :)

5. Being a good citizen and try to hug a creeper. They're not used to it, so they'll freak out and explode. Don't worry though, they don't explode because they think your ugly.

That's it for now, I have to think of more :).
