The beauty of voice-over work is that maybe you come in and record once every two weeks for a couple of hours and do a couple episodes a session. It's awesome! You spend an afternoon playing in the booth and there you have it. It doesn't interfere with much.
When I'm filming survival requires movement. You need your energy and you've got to eat the bad stuff and survival food is rarely pretty but you kind of do it. I get in that zone and I eat the nasty stuff but I'm not like that when I'm back home.
