I was having this conversation with my daughter and thought it was an interesting topic.
If an EMP or solar flare took out everything electronic in the whole world (permanently), how long do you think it would take for you to die, given your current location and circumstances.
I believe my daughter thinks we would live a lot longer than I do, but she is thinking about how long she can live without the internet while I am thinking the world will quickly descend into anarchy.
With no traditional forms of transport, so supplies would dry up, limited resources, health etc, law and order would be a challenge as things become more desperate.
I think I would live for about 3 months. I would try to get the family somewhere safe and remote and come back later, but I think most people would have the same idea.
There’s a fantastic book series based on exactly this: The Change Series. This is a double storyline with the Emberverse series in which the present time beginning in March 1998 loses electricity and “most forms of high-energy-density technology” due to “The Change”, which occurs at 6:15 p.m. Pacific Standard Time, March 17, 1998.
The companion series, which was written first, is the Nantucket Series, in which the island of Nantucket is transported back in time to 1250 BC due to something called “The Event”, the same Event that caused The Change. But— they got to keep all their physics intact.
