Infinite is an old handle I used to use on the 'net ...
Back when the internet was a unix interface, and email was sent using PINE.
Everyone tried to come up with cool monikers; this was the best I could do.
Now, it has a little more meaning for me. I'm a Christian, and I understand that we all have an infinite soul - one that will reside with Christ in Heaven, or endure eternal torment in hell.
It helps me keep a "long term" perspective when daily problems arise.
