My eyes shift when I am trying to remember something .Even when I tell the truth.I think the "eyes shift left or right" idea is a myth.

The direction your eyes/head shifts toward is very real. It's just misunderstood, I think.
When a person is asked a question and they answer truthfully, their eyes and head shift in one direction. (i.e. "What places did you and Travis travel to?" - maybe you tilt your head up, your eyes shift right - when you are trying to remember something that actually happened.)
However, when a person is lying, they shift their eyes and body in a DIFFERENT direction. (i.e. "Jodi, did you stab your bf in the face?" - her eyes shift down, can't keep eye contact, etc.)
So it's not like "Oh well if you're lying you look left." You have to ask the person a few control questions first that they'd have no reason to lie about, to get a feel for how they move/react when they are being honest. Then when you pop the big question, it's extremely noticeable that they're uncomfortable and not being truthful. You'd never even know you did it unless you actually saw yourself on a TV screen trying to lie. It's actually really cool.
It's a part of NLP (Neuro-Linguistic Programming) that cops use when they interrogate - it's called "Kinesic Interviewing."
