Those naps can be a bit disorienting if they're that long! I commend your bravery.

Tell me if you get selected, there are pros and cons just as if you didn't get selected. I know most people don't want to go because it means taking time off their normal work so it sounds like you can take it or leave it, which is an attitude not a lot of people have when they're called. Either way, it's a nice change from the normal hum drum daily grind.
