Remember, you learned it first from a sea creature.
Sex, not piety is the secret to eternal life. So says the Sun based on studies of Turritopsis Nutricula, the hydrozoan. And it you want a more authoritative source, Wikipedia agrees with the Sun. Or, if you prefer hard science you can find this great truth verified in Developmental Biology Online.
The way it works is the hydrozoan de-differentiates after reproducing, basically becomming a baby all over again. Lather, rinse, repeat.
Frankly, I knew it. Piety never felt that good to me, and sex seems ever so much more promising.
