You must leave everything that identifies you behind. Burn off your thumb prints... hope no one has your DNA anywhere. Go way North (Alaska or
Yukon), or way south (Antarctica) and never talk to anyone ever again. Sure it would be possible. But I do hope you have survival training and know
how to hunt.
I think of this often. I know I could disappear, oh my kids would notice I was gone, but they wouldn't worry. They know I am a survivor.
People go missing all the time, and can't be tracked down. Criminals do it all the time. Aliens abduct people.. lots of missing people aren't
found. Lots of people disappear and are still in their home towns....
Yea... it can be done.
