It's excellent cardio and boosts your energy levels so that you can have a brighter day.

And it helps you keep in shape. Too often, we find ourselves going through the motions of everyday life and not really enjoying ourselves. Not only does it make you look friendlier, it reduces stress and improves your immune system. You don't have to be a fitness fanatic to take a walk every now and then.

We blame our unhappiness on our jobs, our spouses, or not having enough money to buy the things we want. Being in good shape always feels better than being out of shape. Remember when your mother forced to eat your vegetables.

Happiness is something we all desire. Fruits and veggies keep you healthy and reduce the risk of contracting many bad diseases. Walking is another thing that does wonders for you. As the old saying goes, an apple a day keeps the doctor away. Smiling just might save your life someday.

While any number of things can certainly contribute to one's unhappiness, the only one that really controls how bibbye you are is you.
