RE: If My Memories Live On, Am I Still Alive?

Like you said, it is very tricky.
For a clone that look exactly like you with your memories, won't the clone start feeling like he is the real deal? For your clone to live on, after old age, it means you will have to create a clone of yourself while you are still young. Which means both of you will be alive or you might consider putting your clone to sleep. I have seen similar stuff like this in movies, hopefully it works that way.
