Counting The Age in Korean Version

For calculating the age, the formula used by the Korean people is: current age = current year - birth year + 1. Plus 1 is there because of all newborns are considered 1 year old. So, I who was born in the year 88 according to the Korean people, my age is 24 years old this year meanwhile in normal calculation my age is 23 years old. Haduwh,, I feel getting older?!? So I won't follow their formula, *hehe*
