The problem with your argument is it rely on the "fact" that we should only
*ever* really live one moment and to expect to be in that moment (either
old or fetuses or whatever doesn't matter)... But life is not a single
moment, it is a succession of ordered moments... so your argument is
absurd. You don't come into existence into a random "moment".
