You stop and pick up a nice hitchhiking girl. Suddenly she loses consciousness and you take her to a hospital. This is stress. In the hospital you are being told that she is pregnant and doctors start congratulating you with the future newborn. You explain that just an hour ago you have seen her for the first time in your life, but she starts telling that you are the father. This is a big stress 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. 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.
