What a difference

It must be psychological, but my tastes have really changed.  For example, I used to love sweet food -- now I don't.  I used to love roasted peppers -- now I don't.  I used to love ketchup -- now I don't.  So far, I haven't found new things that I like that I didn't before, only the opposite.  I'm not complaining, in fact, my relationship with food has changed.  I used to live to eat, now I eat to live.  Not that I don't enjoy food, I'm just not obsessed with it.
