Wrap your head around THIS (and it’s kinda obvious when you think about it) . . . people are freaking out after realizing they’ve been calculating their birthday wrong. You might actually be OLDER than you think. When you turn a certain age, you’re not actually STARTING that age, you’re FINISHING it. So, if you just turned 39, it means you’ve finished your 39th year, and you’re currently in year FORTY.
