It is a number.  Too often we decide that our age - that number determines how we will act, be, think, etc.

Age is but a number - you are how you feel; vibrant, joyful, motivated.  Feel free to run, get dirty with your children or grandchildren - make snow angels or sand castles.

Don't let anyone tell you that because of your age you can not run, skip or hop - stay young in your heart and spirit.
