Wow! This is fascinating! Thanks for sharing and I'm glad you lived to tell about it.
It sounds like you were conscious for a few minutes after being shot -- conscious enough to "play dead" (which seems to have been a great idea!).
If you were armed, do you think you could have mustered the strength to fight back after being shot?
Also, did you pass out from loosing blood?
Finally, is there anything you would do differently if put in the exact same situation again? (no gun)
