This graphic shows how a single persons food stockpile (and his survival time) will be dramatically
halved if he shares it with one other person.
And it'd last just a few days if he had 3 or 4 more people to feed.
Going it alone as a 'Lone Prepper' might therefore be a good strategy so that we don't have to share it with anybody else?
PS- In my cycling days we did a 100-mile ride on a cold winters day, and needless to say I carried a small rucksack stuffed with nutritious food and drink, and had extra energy drink bottles clipped to my frame.
To my disgust, fellow members kept begging me for some of it as we pedalled along but I refused pointblank, telling them diplomatically- "Sorry, I've only got enough for myself".
They didn't like it but I didn't care, it served them right for not prepping, and they were just plain cheeky trying to leech off me!
About 12 of us started, but only a few of us (including me) finished the full 100 miles in about 7 hours and won the much-prized 'Finishers Certificate'; the beggars were dropping out like flies all round the course..
"Do you not know that in a race all the runners run, but only one gets the prize? Run in such a way as to get the prize" (Bible,1 Corinthians 9:24)
