This longevity calculator from MSN, seems to ask the right questions and give me the right answers. It has me living to age 90. Now that's more like it.
This calculator is easy to use. For me who tries to live the "good" life, it has preselected most of the right options - no smoker, constant weight, good diet, etc. But be prepared with your blood pressure and cholesterol level. Also, if you are a man, you'll have to tell it honestly if you have regular proctoscopic examinations. On the negative side, it doesn't ask you marital status or whether you are under stress. Marriage is supposed to be good for you, while stress may not.
