Death is the final stage of growth in this life. There is no total death. Only the body dies. The self or the spirit, or whatever you may wish to label it, is eternal. You may interpret this in any way that makes you comfortable.
There is never a right or wrong time to have kids; it happens for whatever reason, but you can have this paranoia: 'will I be able to do this, I'm not sure if I'm ready to have kids?'
