It’s not like there are people checking for immortals, I think it would be flagged by a dmv employee or something when they dont believe a clear 21 year old is actually 150. Let’s assume it’s current day im caught and not bring speculation on what the US is like in the year 2139 is like.
Continue having children throughout your immortality every 20 years or so. Make sure you have an child of the gender equal to your own, and on their 21st birthday, you switch identities with them. You sit for their picture on their newly issued ID on their 21st birthday, and suddenly its your picture that is the one of record for the legal 21 year old. Your child takes over you identity, grows old, and dies. Repeat ad infinitum.
what happens when the child is immortal too?
Child didn’t have to survive birth. I think that is what happens in highlander, he finds dead children’s names and takes them.
It’s like a ponzi scheme. You take their identity and now they have to start the process themselves
Seems like you’ve given this some thought.
Some of us really liked Highlander
