Self-Defense- Learn to use your fists, feet and weapons to good effect. Weapons, firearms in particular, can be more hazardous to you and yours than an attacker if you are not trained and practiced in their use. You do not need to master a bunch of different disciplines or types, but you should be a capable hand-to-hand fighter and competent with a gun.
Freeze-dried food is nothing new. As early as the 13th century, the ancient Quechua and Aymara people of Bolivia and Peru pioneered a form of the process by exposing potatoes to the freezing temperatures of the Andes overnight, then drying them in the sun. In 1937, Nestlé used industrial technology to create the world’s first freeze-dried coffee, and in the 60s and 70s, the US military shipped freeze-dried food rations to the troops in Vietnam.
