This is a great question: If we knew, what would change? If I knew that when I left for lunch, a car would hit me and kill me, would I go? I'm still hungry - I've seen people receive devastating diagnoses - and be told to change behaviors and they still don't change. I think life is best lived one day - one moment - at a time. Sure, you may have this anomaly and you may also die in a plane crash - I say live your best life and take it as it comes.
