A great gift idea for your dad could be a self-defense course or private lessons with a certified instructor. You can search for local gyms or martial arts studios that offer self-defense classes for adults. Another option is to consider purchasing self-defense equipment that he can use for his training, such as a training dummy or a punching bag. Alternatively, you could get him a book on self-defense techniques or a subscription to a self-defense magazine so he can continue learning and practicing at his own pace.
Or you can get him a star map with the date when he was born.
