While driving through the neighborhood you stop to give a girl a ride.
Suddenly she loses consciousness and you
take her to a nearby hospital, This is STRESS! In the
hospital you are being told that she is
pregnant and doctors start congratulating you, You explain that
just an hour ago you have seen her for the
first time in your life, but she starts telling the doctors that
you are the father, 
already. You require for a DNR analysis and
they make it. Then the doctors tell you silently,
that actually, you can't be a father since you
are genetically sterile (genetically cannot
produce children). This is a STRESS, combined
with a relief. On your way back home you
remember, that you have three kids. That's
what the REAL STRESS is. P.S. What do you do
to your wife when you get home?
