I recently turned 20; hooray for me! As nice as that would be, unfortunately it would only accurate in base 16.

Sigh. I'm actually 32.

Thirty-two is a power of two (that is, 2^{5} = 32), so it stood out to me given my career in computer science (also the number of bits used to represent integer datatypes I typically have to deal with). It then dawned on me that the next 2^{n} birthday I get to celebrate is, of course, another 32 years away. That's a long time to go; but given the life expectancy for Australian men is just over 80 at the moment, I should be able to see it through. I wonder though, what is the probability of actually surviving the next 32 years?

If I understand the life tables properly, and my memory from uni stats classes serves me correctly, multiplying the *p _{x}* values from 32 to 63 should give me the probability of surviving to 64 (since

*p*is the probability of surviving to x+1 years old). That gives me 89.5%. Sounds reasonable, I'll take those odds.

_{x}On to something lighter, I did some really in depth research on fascinating facts about the number 32. And by "in depth research", I mean I skimmed the Wikipedia article while commuting to work. Here are the highlights:

- Fifth power of two (2
^{5}) - Is a Leyland number; a number that can be written as x
^{y}+ y^{x}(2^{4}+ 4^{2}= 32) - Is a happy number, yay! (See below)
- 1
^{1}+ 2^{2}+ 3^{3}= 32 - Relating to chess, both black and white have 32 squares of their respective colour on the board; also the total number of pieces on the board. (Also, I suck at chess.)
- Number of teeth in an adult human, including wisdom teeth. I've had three wisdom teeth removed, the fourth doesn't seem to exist (cue jokes about not being so wise)
- As mentioned, number of bits commonly used to represent integer data type
- Number of bits in an IPv4 address
- Twice the number of kilometers I've ever run in a single effort (so far!)

I'm pretty sure happy numbers and Leyland numbers serve no purpose other than recreational mathematics, but like I said, skimming Wikipedia is about as far as I'm willing to go on this subject.

Here's how 32 breaks down as a happy number:

- Start with 32
- 3
^{2}+ 2^{2}= 9 + 4 = 13 - 1
^{2}+ 3^{2}= 1 + 9 = 10 - 1
^{2}+ 0^{2}= 1 + 0 = 1 - 1 (happy!)

So that was a bit of useless fun :-)
