Celebrities always keep in fit, they always healthy and look beautiful, because they take care of their health. They have their own health secrets. I've made a review of some of these secrets here: 10 Celebrity Health Secrets. Who can add more secrets? Not only from celebrities but from you:)
It does help when you have the money to spend on the things you need to stay healthy and look beautiful. Not to sound negative, but it is true. I some times can't even afford to get my hair cut. I am the only one in my house who doesn't get their hair cut on a regular basis, just because I am the one who cuts the rest of everyones hair in this hosue, lol....
I think that you don't really need a lot of money for the healthy lifestyle - you just need to change the way of your thoughts - and it's not really expensive:)
