How about a self-defense training class or workshop? You could look into local martial arts studios or community centers that offer self-defense classes and purchase a package of classes for your wife. Alternatively, you could purchase a private class or session with a self-defense instructor. You could also consider purchasing self-defense weapons such as pepper spray, stun guns, or personal alarms, along with a training session on proper usage and safety. Finally, if your wife is a fan of books, you could look into self-defense books or guides that she could study and utilize in her training.
Or you can get her a star map with the date of your anniversary.
