When I reached retirement age, I had the option to defer my state pension in return for increased benefits later on.
Part of the decision-making process was to make an estimate of how long I might live to benefit from the extra pension and that site came up with very nearly the same result as I did.
It says I should live to 91. Will human civilization even last another 50 years before it collapses into chaos?! 
Even more so if you indicate a really high income. If your income is high enough it does not matter how much you smoke & eat and how little you work out: you will live forever and need them.
I am glad to read that most people here will get older than me.
Serves you right.
I got 92, which is 30 yrs from now. And I agree with Jasmine’s “Will human civilization even last another 50 years before it collapses into chaos?!” except that I’m sincerely worried about 20 or 30 years before the collapse.
I got 95, but I thought I might have fudged a bit at ‘5-7 drinks per week’, so I went back and set it to the highest setting of ‘8 or more drinks per week’ and it only dropped to 93. I’ll drink to that! 
(not really, still getting over Covid, plus I always do a dry January)
Whoo hoo! I’m only going to lose 2.9 years if I don’t cut back drinking! 
Well, bunky, when the time comes, you’re going to want those 2.9 years! LOL
Bad plan. According to the site, not drinking alcohol actually lowers your life expectancy.
Exercise won’t make you live longer, it’ll just seem like it. 
It says I have 25 years left. Seems a bit excessive, but I suppose it might have guessed differently if it had asked about untreated hypertension. I scored 141/104 yesterday, I’m getting pretty good!
I guess I’m the only one who doesn’t want to know (or even estimate).
mmm
Nope. Not the only one.
It asks like three things that might make a difference. Calling it an estimate is generous.
It gave me 86 with answers of ‘220 lbs’ for my weight and ‘Good’ for my health.
It went up to 88 if I get down to 195 lbs and get my health to ‘Very Good’.
Getting married would up the estimated ages to 91 and 94. That is a huge difference.
ETA: It seems my life expectancy would go up if I increased my drinking. That seems counter intuitive.
83 for me.
It said that I can live longer if I start drinking. I currently average about a six pack a year.
Reminds me of Cliff Clavin’s theory about beer.
My life expectancy? I am bold enough to expect tomorrow, hoping for the whole afternoon too.
I got 92, so I’ve just crossed the half-way mark.
Didn’t try playing with the factors, but the “drink more, live longer” is controversial, with opponents believing there’s no way to sufficiently control for biases such as people cutting alcohol due to health issues.
It says 87.
That is clearly bananas. No male in my paternal line has made it to within ten years of that, and genes are the single biggest factor in your life expectancy.
95 for me. That’s fine as long as I have all of my faculties. I want to be able to read, watch TV, walk, and take care of myself.
