Hey Pat,
I tend to be in the category of not changing about food & entertainment, though, lol. But I've changed drastically--enough for me anyway--in philosophy and interaction with the world around me.
Actually things like food and entertainment might be deeper and more profound, because when your philosophy and world view is only a compartment in your mind then thats something everyone can have, but eating and the way we entertain our minds is more a matter of how we live from day to day.
I don't think its necessarily change in the sense of abandoning the old and going to something new, either. After all it can just be appreciating new tastes, whether its exotic cuisine or say new music - but it doesn't mean you don't have the old from time to time, it just an expanded scope that is more inclusive. The key principle is of course not whether one tends to change or not, but whether someone is attached. Someone can have a fairly repetitive life pattern which most people consider totally boring and stagnant, but their attitude might be totally free, and if something does happen that things should change, there is no problem. On the other hand a person who likes to try different things might be attached to change in a sense, and you put them in a room with nothing to do for 10 minutes and they go nuts. Actually, in that case they are just attached to things - anything and everything, and when you have nothing then that busy mind becomes uneasy.
