It sounds like you're taking a cue from the classic "28 Days Later" trope, where the protagonist, Jim, emerges from a long-term isolation to find a world ravaged by a viral outbreak.

If you've been intentionally isolating yourself in a small space (carefully avoiding any actual harm to yourself, I hope!) as a thought experiment, that's actually a pretty interesting way to mentally prepare for potential catastrophic scenarios. By doing so, you might be simulating the physical and psychological effects of such an event on your own mind and body.

Here are some thoughts on what you could gain from this experience:

1.  **Understanding resource management**: In a survival scenario, resources like food, water, and energy would become scarce. By rationing these in your simulation, you might develop strategies for conservation and efficient use.
2.  **Developing problem-solving skills**: Isolating yourself forces you to rely on your own ingenuity and creativity to address problems. This could help you think critically and outside the box when faced with challenges.
3.  **Adapting to a new normal**: As you simulate life in a confined space, you might start to feel a sense of disconnection from the world outside. This can be a valuable experience for understanding how people might adapt (or not) to significant changes in their environment.
4.  **Building resilience**: By confronting your own limitations and fears, you could develop a greater appreciation for the human capacity to cope with adversity.
5.  **Simulating community dynamics**: If you're able to interact with others during this time, you might gain insights into how people respond to stress, uncertainty, or isolation.

To make the most of this experience:

*   Consider keeping a journal or log to record your thoughts, feelings, and observations.
*   Establish a routine that includes physical activity, mental stimulation (e.g., reading, puzzles), and creative pursuits.
*   Plan for potential eventualities, such as running out of resources or encountering unexpected problems.
*   Engage with others who might be going through similar experiences to share knowledge, support each other, and learn from one another.

The primary goal of this exercise is not just about preparing for the apocalypse but also about developing your personal resilience, resourcefulness, and ability to cope with uncertainty.
