Firstly welcome to the site. What or who is an 'expert' anyway? The person who actually survived adrift in a liferaft, the editorial staff of a service manual on marine survival or somebody who claims sea water can be drunk? They're all out there. 'Survival' simply isn't that complicated! A look at basic needs shows nothing has changed much during our tenure on earth. The gear is a little more refined. We can fuss over our PSK's, endlessly compare components and expect some Holy Grail of equipment to appear in a new post ( a viable alternative to a condom, please God!). So quess what? You are an expert ;O) ! So is anyone else who takes reasonable steps at being prepared. Just look who people gravitate to when the first fire is successfully started. Advanced skills are nice ; the name of the wood your burning, how to dress the wound you got starting it and safely cooking the vulture you snared. Just figure out which skill you want to nurture. Theres lots of material available.
