When Fidel Castro celebrated his 31st birthday he was living in the mountains and fighting against Batista (the Cuban dictator, not the wrestler).
On my 31st birthday, I am living in a comfortable two-bedroom home in the Cardiff suburbs, fighting my urge to eat too many cherry bakewells.
I always feel a sense of melancholy on my birthday -- a feeling that I'm not quite living up to my potential. But then, I've killed far fewer people than Castro. I suppose that counts for something. Happy birthday to me.
