How did I look 100 years before this?

Sometimes you just need your master's hand to what you're doing. Thank you, pulling me out of the shark-impested water or whatever. It's very good. The first thing you can look at is, how do I perceive myself? And if I perceive myself as a person, then can I find this person? If I perceive myself as a body, then how would I look 50 years from now? How did I look 100 years before this? How long can I keep up the way the body looks?
