Remembering past lives

Question:

Why don’t we remember? Dear Deepak I don’t know if you have an answer for this question, but why is it when we incarnate into the physical, we forget our true self or where we were before our birth. We have spent much more time on “the other side” so to speak, then we have spent here on Earth, yet there is not one memory of it. Remembering where we were before we were born would make life so much more enjoyable – there would be no fear of death, and we would be able to accept the death of people we Love with more ease.
Is it wrong to have a huge interest in life after death? Sometimes it scares me, because I feel more of a interest in what could come after this life, then in this actual life
