Being 40

I have decided that I am going to be 39 and thirteen twelfths. It just sounds younger. Amy said I could be like a toddler and refer to my age wholly in months (why do we do that? once a kid has passed their 1st birthday surely we can call them one year old). That would make me just over 480 months. Or she suggested days, just to be really accurate. 14,626 days old (remembering leap years). Its not really helping me feel younger.
