If what doctors say is true:
- then why are they often surprised when people live who are not expected to live, and that people die who are not expected to die;
- then why do many doctors not prescribe for their own families the same medications that they prescribe for other people;
- then why is it that they haven't figured out how to keep people alive for 500 years.
Doctors know a lot of stuff. But they mostly know that they don't know much of how life works.
doctors cant know everything. general doctors only know the general common stuff and they refer patients to specialists if its over their head.
specialists of brain biology dont know much about bone issues so one intelligent doctor in one area is clueless in another
also even with a diagnosis not every patient has the exact same symptoms or level of intensity. there is a spectrum. take cancer. no one can know the exact day someone goes terminal as their are always many factors involved.
for instance people also with dementia may forget medication which increases the likelyhood of being terminal sooner. others feel sick and dont eat and drink so they dont have the energy or hydration to fight it so they also can be terminal sooner.
all doctors know is average lifespan based on numbers.. its an average not a fixed statistic of 100% guarantee.
all they can do is advice what medication, care and diet patients should follow to maximise their lifetime. but they can pick the specific day of death
your expectation is like wanting to be told that you will score 120 on average and you stupidly think i means hitting a double20 three times. and be consistantly accurate
wrong
all someone can do is say you MAY average 120 but that might be
double20 x3 =120
10, trpple20 and the bulls eye =120
triple20 x3 }
} average 120
double20x2 and third dart lands on flaw}
(plus many other combinations over many tries)
so dont bet on always getting tripple20 if someone tells you an average 120 expectancy
as for the 500year old person theory
the medical industry is still young. it has only really been in the last 200 years that things have really accelerated
200 years ago average life expectancy was 35
yep kids being born would never get to know their grandparents uness grandparents gave birth to parents at 15 an parents gave birth to kid a 15 and then the kid might be lucky to know see the grandparents at 5th birthday.. (rare back then)
alot of doctors didnt even have a way to map the genome until the most recent few decades. so i would say expanding life expectancy from ~65-~75 is pretty good work so far for the last 50 years,
many people get to know their great grandparents. i even know someone that has a great great grand parent still alive..
so things have moved on somewhat
