Becoming a zombie is not an easy task, and many of us don't realize that we have become a zombie until very late in the game. To start with, when you become a zombie you will notice some changes in your lifestyle, for example, you will start eating all sorts of things that you never imagined you would eat (a lot of them quite disgusting); you will find that your home environment will change dramatically and that the house will never look the way you used to like it. A lot of your belongings will be trashed and replaced with funny and estrange items.
There are many changes to write them in one post, but other one that comes to mind is that you will notice a big change on the way you dress. Suddenly you will be wearing clothing that used to make you laugh and your old clothing will go to the dump.
If you think about it, feels a lot like marriage.
