Happy 80th Birthday John Byner

By the way, do you mean their body reached the age of eighty years, OR do you mean eightieth birthday?

Think about it, your first birthday your body is 0 years old. You are born, so you aren't 'any years old yet'. When you reach your SECOND birthday, your body is one year old.

I mean, surely being BORN, your day of BIRTH, is your biggest and most real BIRTHday ever. This means, your second birthday you are one years old, your tenth birthday you are nine years old, so your eightieth birthday would mean you are only 79 years old.

So which do you mean, 80th birthday (= 79 years old) or 81st birthday (= 80 years old)?
