26 year old mind with a body age that the varies depending on time travelled? Il explain;

Could depend on how you define time travel I see two options one where the body travels with the mind, the other where the mind travels with out the body , first the (body&mind) If your 26 an just suddenly travel 4 years ahead in time then your still 26 in the sense of how many orbits of the sun you have completed(birthdays) but will you inhabit a timeline with two borzsi96 I donno.The second opinion ,(the mind only) if you suddenly wake up one morning and your in the body of a 30 year old borzsi96 physically u have a 30 year old body but still have a 26 year old mind because u remember traveling; -so the age you "enter' time travel is the age your mind &body/mind or body will emerge but that raise a new question would you age naturally in the phenomenon if time travel isn't instantaneous as iv assume? I donno if that answers any questions but it was an interesting thought an fun to reason out in probably totally wrong .
