Let’s say Time travel to the past is possible. If you were to hop in a time machine and go to the past let’s say 2 years would my age go back 2 years? Like if I went back at 19 would I be 17 when I arrived at my destination? And would I see myself in the past? Or would it just be me in the past? And if I saw myself in the past could I talk to him and help him make better decisions? And if I did would it be on another timeline or would I alter the future of the timeline I’m in?
