How many years?

I just came across a site that asked `How long will you survive on earth?` so I thought, that will be interesting to find out. If you want to try it, you`ll find it here. So, for curiosity`s sake, (not that I believe in these things) I just had to have a go at it.
The result was that my life expectancy,if I believe it, will be 84.
Keep reading my blogs and if they stop appearing in the year 2037 you`ll know this test was correct!
