I recently stumbled upon these online tests: Life Expectancy and Real Age. Both sites are the same concept, you answer a bunch of questions about your health and lifestyle. The life expectancy test tells you what age you might be likely to die, based on your current answers and the Real Age test tells you what age your body thinks it is based on how you live. I just thought it was fun and interesting.
My Life Expectancy: Age 84
My Real Age: 25.8 (my actual age is 25.3)
Not too bad. I guess mine are good because I don’t smoke, rarely drink, and keep active.
Fascinating! Thanks for posting.
I got 94 on life expectancy, but can’t take the real age one because its only for people born before 1989
I have the same life expectancy as you do
And I’m apparently younger than I thought 
My real age is 19.9 (and the actual one 21.6)
