There are at least two pathways to continue your presence. One does not involve human cloning. Without going into telomeres and ribonucleoproteins, let me just say that science is actually close to finding and checking the aging gene. Someday, you might be able to take a pill and stop growing old. The question is, can this technique be perfected before you get too old? You can still, then, of course, get killed in an auto accident or through an illness, but that so-called 130 year old lady from Georgia (of the former Soviet Union) could someday be commonplace.
