Binary Birthday

It’s my birthday today and this year it’s a binary birthday.

I haven’t had one for sixteen years and won’t have another for thirty-two years.

For the past sixteen years, I’ve been 2⁴ + n : where (0 ≤ n ≤ 15).

Today I’m 2⁵.

That means I now need a whole extra digit to represent my age in binary.

Yesterday I was 11111.

Today I’m 100000.

Egad.

But I’m only 20 in hex …
