The Death Clock seems to just invent a date at random. I entered my data, and it gave me a death date in the year 2056. I reduced my BMI (because I could stand to lose some weight) to what that would gain me, and it gave me a date in 2047. Re-entered my original BMI, and now it gave me a date in 2058. Changed nothing, but clicked the button again, and got a date in 2053.
All told, I got dates in about a 12-15 year range with the same set of data.
