Age expectancy - or when am I scheduled to die?

Age expectancy
The National Statistics Office publish this information, but something has always intrigued me - their figures don’t take account of the future trends - so what happens if you try to model future performance based on the past?
This looks like a fairly straight line, and indeed we can fit it with y=0.2648x+67.871 (R^2 = 0.9944) which means I am actually due to peg it at around 92 years of age. Ignoring things like medical history and lifestyle, of course, as these are averages from the population we are dealing with here.

Not today, it seems. Bit cheeky amplifying my own post, but a clip from @egoldstein reminded me about it

hmm - when I use your two different formulae, I make your life expectancy 79-80 years in both cases! The first formula gives me just over 80 and the second 77!
7 months agoy=0.2648x+67.871
y=x
So, substitut... more
Not sure how you are using it then! You need to work out when my actual age exceeds the age expectancy line; so you have a pair of simultaneous equations,
7 months agoy=0.2648x+67.871
y=x
So, substituting y for x in the first equation we get
y=0.2648y+67.871
0.7352y=67.871
y=(67.871/0.7352)=92.316
Thanks for posting this Pat…does this change based on whether Obama’s health insurance plan gets passed?
7 months agoaaah! i was using them as straight equations.
