Scientifically speaking, the human death rate is a surprisingly low 93%. This is the obvious calculation: the number of people who died divided by the number who were born.
I have found no evidence against it to date
Ahh, "immortality" strictly defined.
Mayhaps you have found evidence that you are not the earliest-born person to have eternal youth?
Is being certain of one's im/mortality similar to the Halting Problem?
Why no, the first immortal was born months before me.
Yes, all the way until age 40. Then, reality.
That sounds like it is biased towards people who haven't lost their parents by age 40. For people (like me) who have lost a parent before hitting the age of 40 it becomes more real sooner.
I assume clarge1120 meant that people feel immortal until 40 because their body generally does not stop them from doing things until one’s 40s.
Hmm it seemed unclear. I guess I am totally unlucky as im 35 and my body is already acting that way.
