I hoped to find a Chuck Norris joke in this thread.
It's possible to be immortal in physicality, but not really probable, our plane is like every other plane a certain vibration - consciousness could mantain it consistently if it wishes, though you can't switch by definition to another plane with a different density while remaining physical. You can't perceive what you are not the vibration of.
What's more probable is that you went through an ascension process and then be able to change your vibratory rate however you desire. For example Saint Germain did that. He presented himself as Count of St. Germain in France somewhere in the 1700s, even though many years have passed people wondered why he never run out of money and why he didn't age. Today you find it under the 'myth' category like most things that don't fit with our limited version of reality
