+ Charlie Posted June 28, 2023 Share Posted June 28, 2023 (edited) What I found interesting in my case was the patterns for my father and for my mother seemed to go in opposite directions in relation to their parents' lives, therefore I wondered how one would project the pattern for me, if one assumed that there was a mathematical formula for dealing with the correlation between my likely pattern and their actual patterns. For instance, does one add up my progenitors' ages at death and take an average? Does one look for certain medians? Does one factor in my gender? Etc., etc. Does one simply say, "You have already lived longer than your father and you probably won't live as long as your mother." I have usually figured that I would split the age of death for my parents and expect to die at 87. Edited June 28, 2023 by Charlie Link to comment Share on other sites More sharing options...

Your father's age of death can't be factored in because he died not of old age, coronary disease, stroke, etc., but of something unexpected, which you're unlikely to get. It's as if he died in a skydiving accident--not part of your genetics (though there are some forms of leukemia which are inherited, and I'd wager you'd be told). Your mother's more advanced age likely had much to do with advances in medical science and life expectancy in general. Absent other illnesses/accidents, telomere length is what determines longevity (and probably also gut microbiome, much of which is inherited), so the longer lifespans are more telling.

+ Charlie Posted June 28, 2023 Share Posted June 28, 2023 In other words, any reasonably accurate mathematical analysis would require an enormous number of measurements more sophisticated than simply age at death of one's progenitors. keefer 1 Link to comment Share on other sites More sharing options...

+ Charlie Posted June 28, 2023 Share Posted June 28, 2023 (edited) OK, so I will probably just go on splitting the difference between my parents age at death, and prepare to die at 87.

[This particular question has arisen because my spouse keeps asking, "How long do you think I will live?"

Your mother lived well beyond the average female life expectancy of her day, as did both of your paternal grandparents (your father doesn't count, since he death was unexpected and not related to his genetics). I seem to recall from prior conversations that you're about 82. Even using standardized tables, you'd be expected to make it to 90. But your genetics points to longevity. Of course, your own medical history is critical information--more so than family history. Of course, one can never be certain of anything after 80.

CuriousByNature Posted June 28, 2023 Share Posted June 28, 2023 I used to work with a lady who had a big birthday party when she turned 43. The sad reason was that she had surpassed the age of both her parents when they had died (mother 42 and father late 30s). And if I remember correctly several of her grandparents also died very young - only one was living when she was born, I think). But thankfully she is happily enjoying her retirement and is now in her late 60s. prof, + Charlie, Marc in Calif and 2 others 5 Link to comment Share on other sites More sharing options...

Everyone is more or less familiar with a chess board with its 8x8 pattern of alternating black and white squares. The question is, how many distinct squares can be identified on a chess board? A hint is that there are 64 of the single squares and 49 2x2 squares. 8x8 + 7x7+6x6+5x5+4x4+3x3+2x2+1X1 I believe the math shorthand is 8to the second !
