Is that normal that my MBP starts in 64 bit?

I was just wondering if all the MBPs start in 32 bit or 64 bit?

Most of my processes are in 64 bit. Does it use more battery life?

Considering Snow Leopard is 64bit...yes its normal. It doesn't matter what machine you have if your OS is a 64bit OS it will run 64bit programs.

From a practical standpoint, no, running 64-bit apps will not reduce your battery life.

CPU-intensive applications will force greater battery usage, but that's the same whether you're running in 32-bit or 64-bit. However, you COULD argue that running an app in 64-bit mode means it's running more efficiently, finishing the process faster, and thus maybe even using LESS battery life overall.
 
It's most likely you're running in 32bit mode. From what I've read, all MBP's come shipped in 32bit mode. As others have said, OSX will still run 64bit apps when available.

To check if your kernel is 32 or 64bit, go to System Profiler. Choose Software and look at "64-bit Kernel and Extension" in the right window pane.
 
Thanks guys. It looks like I am running on 32 bit.

I know you're suppose to hold 6 and 4 when you start up the computer to get into the 64 bit mode. I don't think I ever done it.
