Happy birthday! You were added in 1.0.5 on June 23, 2011, so you're 12, and since you're 23, 23=12! So 11=0, and if 11=0, (11 times 1/11)=(0 times 1/11), and 0 times anything is 0,
and (11 times 1/11)=1, so 1=0! And if 1=0 and 11=0, 1+11+11=0, and 23 is 1+11+11, so you are 0 years old!
Happy 0th birthday!
