Every man should have something of the survivalist in him. Every woman is looking for a man who can build a tent in the forest out of sheeting- and every wise employer is looking for the same thing.
It is possible to start small. Survivalism is not a matter of gadgets really. You may like to buy a walkiing kit like the one above. It contains some surprisingly useful items such as a saw (for cutting brances to make a shelter)and will fit in the pocket. It also contains a firestone- a sort of inexaustable waterproof metal match.
Never show your gadgets to women! Only boys understand.
