I think that people just don't understand how great it feels to take care of yourself. Yes, fast food tastes good. Yes, candy bars and hostess cupcakes are delicious. Yes, it is nice to sit and do nothing all day.
But when you fuel your body with veggies and lean meats and fruits, you feel wonderful and strong. When you finish a tough workout for the first time that you have been working up to for months, you feel exhilerated! When you finally get that definition in your quads, your tricep or whatever without having to flex what can take your smile away?
Isn't it wonderful to be able to keep up with your kids, and in some cases here, grandkids? When you take care of yourself you get a sense of pride that people who don't w/o can't understand. If they really did, they would say, "Good for you! I am so happy that you are doing something that you enjoy!" or when you are in the checkout late with your vid the clerk would say "OH! That is how you look so good!" instead of critiquing your purchase (which IS none of her business anyways...) That and there were some great comments about insecurity above.
Pinky, you should arm wrestle your bro! That would be fun!
