I think that no body is equal to another, so not all people needs the same amount of exercise or not even a same diet. Wich is convenable for ones is bad for others. For example, in my case, I don't need any diet. I'm too thin even if I eat normally. I even force myself to eat more and more to win some wieght. My physician said it's O.K, since my body is just this way and I will not get fatter. And of course, if does too much exercise I will become thin as a stick! So, it's better for me not to do it...and that's good enough, since I rather like to read than to go to perform trekking! But physician said it's O.K too, since I walk a lot and also dance which, he saids, it's like to perform gym.
In fact, my physician saids that nowadays people believes there's an only way to be healthy and for him every person must have his/her own recipe, since every body is different from another. Who suits A could not suit B.
My opinion about Sissi is that if she was not an anorexic, she was very near of becoming one. She was in love with herself. I like her very much but there's also little things of her I don't like too much. She was intelligent and sensitive, but also excentric and she seemed not to care about other people feelings.
