If Botox, collagen injections or plastic surgery aren't on your top list of to-do's to help yourself look younger, read on. You don't need to take extreme measures to reveal a more vibrant you because there are many simple and natural ways to refresh your appearance and help you look younger.

One of the first things I recommend is to put your money where your mouth is, literally. Fix your smile. A recent national survey conducted by Roper Public Affairs found that more than six in 10 Americans (62 percent) believe straightening crooked teeth can make an adult look younger and 77 percent agree that doing so is one of the best investments a person can make in improving one's appearance.

Don't just focus on your face to look younger. Think about your body, too. There are many inexpensive and fun things you can do to your body to look younger and feel your best. Some of my top tips include:

* Wear brighter colors. Adding color to your wardrobe makes you look happier and feel more alive. Let everyone else wear depressing black to the reunion.

* Stand up straight. You'll instantly have a better body.

* Work magic with body slimmers. These undergarments make you look thinner in a matter of moments.

* Mess around at the makeup counter. Have fun at the make up counter. Get makeovers and advice. Take pictures of yourself to see what looks best.

My final advice is to just be honest and accepting about who you are because people can see shame in your game. And most importantly, make sure any investment you make is the best one for you.
