Quiz: How Long Will I Live?
A simple way to estimate your lifespan
The following quiz, based on behaviors of the long-lived Seventh Day Adventists, is adapted from one created by Thomas Perls, a geriatrics specialist at Boston University. It’s good, not perfect.
“People will write to me and say, ‘I love the calculator, but it says I should be dead,’” Perls says. “I say, ‘This probably means you had some pretty bad behaviors in the past, but the good news is you have fantastic genes that protected you from them.’”
For the following test, start at 86 if you’re male and 89 if you’re female. (Sorry, fellas: Women typically live longer than men.)
