It's fine to be 20 and have fun - as long as you're prepared... It's like the grasshopper and the ant.At least some other Candians get it. Can't say the same for my girlfriend or many of my friends. But at 20 years old, who the hell wants to be a prepper?
Sorry, let us add some info.
First I went and bought quite a bit of canned goods and bulk products from Superstore. Now I just get extra groceries every time I am there. I have nowhere near 1 year's worth of food, but I do have food, water, and ways to prepare and consume it squared away. Remember, 1 years worth of food will do you no good if you freeze to death, are dehydrated, can't protect it, or it goes bad. Work towards overall preparedness, not just food. Get water, protection, fuels, and food, and work from a week prepared, to a month to 6 months and so on.
