In my experience- adults die right on schedule. If an MD tells a patient they have 6 months to live - you make bank on the fact in 6 months they’ll be dead. Kids - however- no one gives kids this kind of information. They get up everyday & live. Until the day they die. And that’s often later than anticipated. Sometimes a prognosis becomes a self fulfilling prophecy. It’s the weirdest thing. I couldn’t make a blanket statement about choosing or not choosing treatment. It would depend on the diagnosis & more importantly- what was going on in my life at that time. I’d certainly get treatment if it meant I had a better chance of extending my life to be around for a big event - graduation- wedding- birth. Even folks with stage four cancers can extend their end date- sometimes by years.
