Changing The Rules

It really isn't fair. After almost 50 years it shouldn't be possible for the rules to change. Not when it is in regards to your own body. They do though. At least, they do for women. I feel like I no longer know my own body. Things that used to be, are not anymore when it comes to metabolism, energy, abilities. I still force myself to do things, but my body protests to the point of extreme pain. Then, I think I'm being great, and working out hard doing things, and I still either do not lose the pounds I want to, or actually end up gaining. A lifetime of learning how to deal with your body should be enough, but it isn't, because right when you do think you have at least that under control... the rules change.
