Scientists at the University of Connecticut have created a calculator that will predict how many healthy years you have left. Now how long you'll live, but how long you'll be healthy.
You answer some basic questions about yourself--age, sex, education, whether or not you smoke, exercise...that kind of thing--and it spits out data.
For example, Say you are a 36 year old. never smoked, eat pretty healthy, and exercise 4-5 times a week, but drink and don't get enough sleep. It said healthy until 57. But then it said live to be 93. Am I wrong for thinking that's not so great? I mean, who wants to kick around for 35 more years if they're falling apart?!
I tend not to put too much stock in this kind of thing, but it's still interesting.
