Here we go with another ground breaking study that helps you decide when to be what and for how long.

It turns out your life happiness peaks about twice.  Once when you're too young to realize how good you have it and again you're old enough to realize your most miserable days are yet to come.

A new study has found there the average person's happiness peaks at ages 23 and 69.

In your early 20s you're optimisic about the future. Plus, you still look great and have no problems recovering from a long night out.

In your late 60s, you find some contentment and come to terms with your regrets. You also appreciate the health you've got because you know it's a blessing and the clock is ticking.

People hit their MOST miserable point at age 75 and after.
