2B or not 2B...

Today, March 1st, 2011, is the sixtieth day of the year. In hexadecimal notation that's day 3C. For certain practical purposes that means that even though my birthday falls on February 29th, I am now 43 years old. That's 2B years in hex. I'm sure most of you can already see where this is headed.  

Practicality aside, since my actual birthdate is like a perpetually underachieving Brigadoon, showing up just once ever four years, many folk insist that I must be something like ten-and-three-quarters.  

So what is it? Am I 43 or not? Am I 2B or not 2B?

I'll say this much... I'm feeling pretty rough around the edges for a ten-year-old, but even with pneumonia I'm feeling pretty spry for forty-three. Whether or not I am 2B, I plan to be the heck out of what I am.
