Try both. http://www.deathclock.com/ or http://www.gotoquiz.com/special/when_will_i_die.html. I took both tests and they say ill die somewhere around my 70's (70-74). The second test was a little harder to complete. I'll have to ask my mom more about it. I filled out a few of the questions though and was given almost the exact same answer as on the first test
