Please don't. I know you live in the fake plastic woman capital of the world. You do not have to join the membership club.
It starts with botox. Then it is a nip here, a tuck there, fill up the boobs, get a fake butt, and start getting spray on tans. Before you know it you have suddenly turned into a failed science project that scares little kids on the street corner.
Be bold. Be brave. Let aging happen naturally. Besides, I am sure your husband will still always adore your awesome craziness no matter what you look like.
Also, from what I remember of you posting pictures of your mom when she was visiting. You do not have anything to worry about, because you have good genes too.
Either way this is a long winded way of saying you dont need botox. Eat healthy, work out, and do your best to live a good long life naturally. No one stays young forever, but the beauty within will always shine through when you continue to treat your body as best as you can.
