Freebased in the middle of the night?
Can knowledge and skills be taken away from you? Not in the same way as a physical object. But I do not personally believe that is the critical aspect for Survival and Preparedness. A survival or crisis situation can take place at any time or place. And it often takes place when you least expect it to. You may have to face the situation empty handed.
Its up to YOU. Not your gear or possessions. You have to make it through this situation by using your skills, experience, knowledge, endurance, strength; mind set and will to survive. The idea that stockpiling supplies would be the best way to prepare I do not share. Equipment can be very useful, no question about that. But it’s YOU that must be able to utilize this equipment to its full potential.
Knowledge is also about understanding risks and what you can do to reduce them. Know your local terrain, climate, seasonal variations; setting, culture and making them work to your advantage. Is also about knowing yourself, your limitation and actively working on strengthening your weaknesses.
