in all seriousness, even if you are the only one who has it? I would imagine even 500 years from now the average person would be so different in terms of language, patterns, likes / dislikes etc you'd feel like you were of a different species or at-least a fish out of water. If you dared mention such ancient technology as a Smart Phone they'd probably think you were taking special pills from Jupiter. Not to mention, seeing everyone you know come and go? and then experience that cycle, again and again and again.
My assumption before was based on the idea that human lifespans just increased to 1k years. But I would imagine being the only one who has it, that'd be a brutal life even if you are 100% healthy and at your prime years.
