A: not as something perceivable by the individual. either there is nothing at all, or some great big "soul merging" christianity style. i don't really believe in the existence of the soul either, and i don't find it exceptionally likely, so overall i'd say individual life ceases at the moment of death.
if there were an afterlife: no, thank you. i've had enough already.
Q: how do you usually face tragedy?
