Weaknesses of Modern Self-Defense
The over-reliance on technology is a major weakness. Relying too heavily on gadgets and gizmos can make you a sitting duck in a real-world self-defense situation.
The skill degradation from relying too much on technology is another major weakness. The more you rely on a device, the less you practice actual self-defense skills.
The assumptions of safety are another weakness. People often assume that technology will always be available and working properly, which is not always the case.
The practice and mindfulness of self-defense is the best idea. Regularly practicing self-defense techniques and being mindful of your surroundings can make you a more effective and confident defender.
