How long can you live in a tent?
As long as you like.
As I told you above, in the event of an emergency, you start moving away from the point of the nuclear explosion and from the area toward which the wind is blowing, since that is where the radioactive contamination zone will be.
Of course, it is best to move somewhere where you have, for example, a house, a country home, or relatives.
But not everyone has that option.
Moreover, history shows that deranged people may simply seize all of this. That is, take over a house, a car, and so on.
Therefore, living inconspicuously somewhere in the forest is the best option.
An emergency backpack can hold three months' worth of food or more if it is dry or freeze-dried food. Naturally, you will need to ration it and eat only small amounts.
You can purify and boil water yourself. I already mentioned this a little earlier.
Naturally, all this survival gear costs some money. If you invest in good equipment, it will cost around 500–700 dollars.
By the way, this is another reason why your relatives may try to dissuade you; I wrote about it a little earlier. “Why are you wasting money on all sorts of nonsense!!!” Well, you understand...
And by the way, I gave you a survival course in
2011 year. There is a lot of useful information there:
Your Yoga. Survival Practices.
You can even live in a tent in winter!
But the tent needs to be modified a little.
Although someone is already trying to produce them. BUT they are heavy.
Yes, they literally replace a small cabin. They are essentially complete residential houses. So the weight is justified.
But personally, I would not consider one something you would have to carry on your back for dozens of kilometers.
If you wish, you can find a tent stove. They are also made as light as possible. As I mentioned a little earlier, there are ultralight tents that can accommodate three people if necessary, despite being designed for two. It is cramped but possible. Three- or four-person tents, however, are already very heavy.
And in general, forget about the car. Many people keep thinking about it, I know. Just forget about the car. It is not there. There are NO more cars.
There are you and your legs. And what matters is how much you trained at the gym

I talked about training and sports for many years on the Your Yoga website and in my Ashram. I hope you listened to me.
Do not forget the information I gave you in 2012 on the Your Yoga website about dome houses.
Your Yoga. Video: Geodesic Dome House (Spherical). Building the Perfect Home.
It clearly says that some peoples of the world ALWAYS live in yurts, such as the Yakuts. And if you are afraid of living in such conditions for a while, they LIVE that way their entire lives. What you are afraid of is their ordinary LIFE.
Yes, these stoves are small. But their main advantage is that they weigh only a couple of kilograms. And they are easy to install in any tent, or at least near the tent entrance.
Yes, you will have to fuel them with small branches and twigs; logs will not fit.
A small ax will solve that problem.
Stove names:

You can find them by these names if needed.
