From my friend JO

The exercise is vital for all the reasons you already know, but it's more than that. If I am feeling the weight of the world, it is magically lighter by the end of the hour.  It's fun and it makes me feel like I am a little girl again in dancing lessons.  Who doesn't like to feel younger?  I look forward to the comradery with the other ladies and am inspired by them.  They are all ages, shapes and sizes.  There is one lady who is 87 and has been coming for 30 years. She can do it because she has never stopped. The ones who are more fit inspire me to go on,  the ones that need more work make me feel good about myself.  Hahaha!  The point is, whatever shape you are in...you will fit in.  It's every morning at 8:30.  I commit myself to going 3 times per week, then my husband and I walk town lake every Sat morning.  (I agree with the nature thing!)
