Truthfully, no one can tell you whether you’ll live to 100 – but lots of people are willing to take a guess. This ‘Living to 100 Expectancy Calculator‘ is more sophisticated than most, requiring you to answer 40 quick questions about your diet, lifestyle, current health and family background. It’s got some decent science behind it too, having been created by Dr Thomas Perls, the director of the New England Centenarian Study – the largest study of centenarians and their families in the world.
Does it perhaps err on the positive side? When I completed it recently I was told I would live to 92, which is higher than most other similar tests I’ve completed. But, hey, I’m not arguing.
If you want a slightly different take on living to 100, this simple tool from the Office of National Statistics will give you a probability of you reaching the magic age.
