Many Americans work side by side with space aliens who look human -- but you can spot these visitors by looking for certain tip-offs, say experts. They listed 10 signs to watch for:
1. Odd or mismatched clothes.
2. Strange diet or unusual eating habits.
3. Bizarre sense of humor.
4. Takes frequent sick days.
5. Keeps a written or tape recorded diary.
6. Misuses everday items.
7. Constant questioning about customs of co-workers.
8. Secretive about personal lifestyle and home.
9. Frequently talks to himself.
10. Displays a change of mood or physical reaction when near certain high-tech hardware.
Ummm... I do most of the stuff that's listed here. Am I a UFO Alien in denial then?
