Possibility of Seeing Your Next Birthday

In response to my diary piece, a kind reader has sent me the relevant

actuarial tables (though from 1983). Here is a subset of them. The meaning

of, for example, the “60″ row is: Of every 1,000 males aged 60 in 1983,

9.158 were destined not to make it to 61. It is indeed the case that at age

105, your chance of making it to your next birthday is only 50-50. Is it

me, or is there something a bit creepy about the actuarial business? An

actuary once told me that I would most likely die in October of 2026 (I

think that’s what it was). I’d really rather not have known that.
