Is all DNA the same size? All genes identical in size? Sometimes I think the gene for FEAR must be huge in some people. Why?

Because they NEED to have loaded guns available 24/7 to feel "safe".

The non-guns aren't fearless or filled with bravado. The non-guns just don't think about it.You have to THINK ABOUT being unsafe and think about possible threats and think about being harmed to be fearful. Being AFRAID 24/7 is not my idea of heaven.

Is it bravery or bravado or lack of awareness? I dunno what it is but it's something.
