Birthdays often rank among the most-hated milestones for many of us, reminding us we're another year older—and are often wearing the signs of our advancing age, too, from aches and pains to those extra pounds around our waistlines.
And while there's no turning back time, there is a way to ensure every birthday is better than the last, no matter how many candles you're blowing out on that cake.
