I like the idea of an old soul. I once allowed myself to be hypnotized for the purpose of past life regression by a medium. We were able to see a past version of myself set during the Roman era. I guess that would make me an old soul. But my appearance, I get from my mother and remain looking about 8 years younger than I am. I remember one time, someone asked my mother why she married such an older man. At the time, she was 47 and dad was 50. She looked 40 and he looked 60 because he had a rough life.
